Loading data from HDFS does not work with Elephantbird - hadoop

I am trying to process data with elephantbird in pig but I don't succeed in loading the data. Here is my pig script:
register 'lib/elephant-bird-core-3.0.9.jar';
register 'lib/elephant-bird-pig-3.0.9.jar';
register 'lib/google-collections-1.0.jar';
register 'lib/json-simple-1.1.jar';
twitter = LOAD 'statuses.log.2013-04-01-00'
USING com.twitter.elephantbird.pig.load.JsonLoader('-nestedLoad');
DUMP twitter;
The output I get is

This seems to be a general problem with the pig version shipped with Cloudera 4.6.0: the problem seems to be the line that says
[main] ERROR org.apache.pig.tools.pigstats.SimplePigStats - ERROR 2997: Unable to recreate exception from backed error: Error: Found interface org.apache.hadoop.mapreduce.Counter, but class was expected
I got a similar error when running another user defined function for loading data:
[main] ERROR org.apache.pig.tools.pigstats.SimplePigStats - ERROR 2997: Unable to recreate exception from backed error: Error: Found interface org.apache.hadoop.mapreduce.TaskAttemptContext, but class was expected
When I force pig to local mode (''-x local'') I get the more obvious error
Caused by: java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.TaskAttemptContext, but class was expected
So the version of Hadoop pig uses seems to be incompatible with the one shipped with Cloudera, I guess.


This is indeed a versioning problem: some libraries are not yet compatible with the new MapReduce API, see for example the issues #56, #247 and #308.
For ElephantBird the issue is solved in a recent version. Using ElephantBird 4.1 in the above code and adding the Hadoop compatibility module
register 'lib/elephant-bird-core-4.1.jar';
register 'lib/elephant-bird-pig-4.1.jar';
register 'lib/elephant-bird-hadoop-compat-4.1.jar';
register 'lib/google-collections-1.0.jar';
register 'lib/json-simple-1.1.jar';
solved the problem! :-)

Having trouble Loading a multilevel JSON file into Apache Pig and saving it as csv

I'm super new to apache pig and was trying to load a multilevel json into pig and save it as csv.
Json file I have - home/vikaspattathe/dataset/sample.json

Opened pig from the the directory(incase that is of any concern) - /home/vikaspattathe/dataset/
I tried the below commands to load the data and getting following errors.
grunt> sample_table = LOAD '/home/vikaspattathe/dataset/sample.json' USING JsonLoader('id:chararray, reviewerId:chararray, asin:chararray, reviewerName:chararray, reviewText:chararray, overall:int, summary:chararray, unixReviewTime:chararray, reviewTime:chararray, category:chararray, class:int');

The load wasn't successful.
Also, is the below command correct for storing the file as samplecsv.csv, once it's successfuly loaded.
grunt> STORE sample_table INTO '/home/vikaspattathe/dataset/samplecsv' USING PigStorage(',');

HDFS doesn't have /home file paths. User data is stored under /user paths. As the error says, the input you gave doesn't exist in HDFS.
If you want to load local filesystem, then prefix the path with file://
You also don't need HDFS to use pig, if you start it with pig -x local
As for the output, start with
X = LOAD '/tmp/sample.json' USING JsonLoader('id:(oid:chararray), reviewerID:chararray, asin:chararray, reviewerName:chararray, helpful:tuple(int), reviewText:chararray, overall:int, summary:chararray, unixReviewTime:long, reviewTime:chararray, category:chararray, class:int');
But I don't know how helpful field should be added for arrays... I tried helpful:[int], and that produces the same result.
\DUMP X;

Pig script doesn't work with MapReduce

I'm trying to use Hadoop and Apache Pig. I have a .txt file with some data and a script .pig file with my script :
student = LOAD '/home/srv-hadoop/data.txt' USING PigStorage(',')
as (id:int, firstname:chararray, lastname:chararray, phone:chararray, city:chararray);
student_order = ORDER student BY firstname ASC;
Dump student_order;
And this is my .txt file :

Bit, if I execute : pig -x local data.pig --> it works fine
I missed something ?

Hey It seems that your 'data.txt' is on your local file system. When you run 'pig -x mapreduce' it expect input to be in hdfs.
Since '/home/srv-hadoop/data.txt' file is on local file system your 'pig -x local ' is working.
make directory on hadoop filesystem:
hadoop fs -mkdir -p /home/srv-hadoop/
copy your data.txt file from local to hadoop
hadoop fs -put /home/srv-hadoop/data.txt /home/srv-hadoop/
now run you pig in mapreduce mode. It will work fine

You have 6 fields in your file and the schema that you have specified has only 5 fields.You have another field after lastname,age perhaps.Modify your load statement like below.
student = LOAD '/home/srv-hadoop/data.txt' USING PigStorage(',') as (id:int, firstname:chararray, lastname:chararray,age:int, phone:chararray, city:chararray);

You can try this: pig -x mapreduce file://data.pig

How to resolve the following apache pig error?

I am executing the following commands:
A= load 'user/cloudera' using PigStorage(':');
foreach A generate $0,$4,$5;
dump B;
On executing the last command I get the following error which I am unable to resolve.Being a newbie to bigdata and apache hadoop stack,I am unable to comprehend this error.Please help ASAP.Also searching on StackOverflow for similar errors did not help:

Details at logfile: /home/cloudera/pig_1447424730804.log

Solution:
Change line 1 of your code to:
A= load '/user/cloudera' using PigStorage(':');
Having said that, are you sure your input data is in your home area? That seems unlikely. It's more likely to be in a folder within your home area, i.e. /user/cloudera/input-data.
Before running your job do:
hdfs dfs -ls /user/cloudera
to confirm that input data is actually in that folder. If it's not, work out where it actually is, and make sure it is on the HDFS and not locally.
Explanation:
The relevant part of the logs is
ERROR 2118: Input path does not exist: hdfs://quickstart.cloudera:8020/user/cloudera/user/cloudera
This suggests it's related to the input path. The part of your code that deals with the input path is
A= load 'user/cloudera' using PigStorage(':');
By not adding a forward slash to /user then it assumes that everything is relative to your home area, so for example writing load 'input' would lead the Pig job to read in hdfs://quickstart.cloudera:8028/user/cloudera/input. In your case then the missing slash means it adds it to your user area.

Please check where are you running pig statements in local/linux mode or mapreduce mode , if you are running local mode you cant read HDFS file
run this cmd $ pig -x mapreduce
after this
Grunt> A = load '/;
Grunt>Dump/store /

If you look at the above error code (copied from question that was posted), input file path is taken by pig as below
'hdfs://quickstart.cloudera:8020/user/cloudera/user/cloudera'
So when running pig in mapreduce mode and using quickstart VM, you have use
'hdfs://quickstart.cloudera:8020' before your input file path....
Is the input a folder?...if so pig script will read all the files in the folder....
Example:
say your input file path which is located in hdfs is '/usr/cloudera/inputdata.txt' then your query has to be
A= load 'hdfs://quickstart.cloudera:8020/user/cloudera/inputdata.txt' using PigStorage(':');
foreach A generate $0,$4,$5;
dump B;

The only thing that u have to check is the file path.
hdfs dfs -ls /
check how the path structure comes.
like ..../input/data/file.
file u are going to use.
A = load '/input/data/file';
dump A;
only thing is the proper path of your file that u want to load.

I had a similar issue and I was able to fix by deleting the passwd file from the target folder and then copying it again using the correct relative path:
A= load '/user/cloudera' using PigStorage(':');
The instruction in the video is missing the '/' before the user
Step 1:
hdfs dfs -rm /user/cloudera/passwd
Step 2:
A= load '/user/cloudera' using PigStorage(':');
Then followed the instructions from the Coursera video.

How to Import/Load .csv file in PIG?

lets suppose there is a text file tab limited (datetemp.txt) I want to load this text file in pig for processing but when I am typing below line its giving me error as :
grunt> inputfile= load '/training/pig/datetemp.txt' using PigStorage() As (EventID: chararray,eventdate: chararray,count:int);
grunt> dump inputfile;

Please help me here..!!

PigStorage is case sensitive. Use PigStorage and not pigstorage.

Your question headliner said you were trying to load a CSV file. For that, I've had good luck with using org.apache.pig.piggybank.storage.CSVExcelStorage() in my LOAD statements as demonstrated at https://martin.atlassian.net/wiki/x/WYBmAQ.

Why don't you write PigStorage('\t') as you have mentioned already you have tab delimited file instead of PigStorage()
Mentioned code -
grunt> inputfile= load '/training/pig/datetemp.txt' using PigStorage()
As (EventID: chararray,eventdate: chararray,count:int);
May be this might solve your problem.
let me know if it is something else.

hdfs://192.168.195.130:8020/training/pig/datetemp.txt
file wat not found in your hdfs!! make sure the input file to be placed in the above location.

Have you checked whether the input path exists?
Try:
fs -ls /training/pig/ in Grunt Shell
if it displays datetemp.txt in the list then it will work otherwise give proper input path

Log is telling the ERROR clearly.
org.apache.pig.backend.executionengine.ExecException: ERROR 2118: Input path does not exist: hdfs://192.168.195.130:8020/training/pig/datetemp.txt
Can you check the file exists in HDFS or not?
You can also check your pig is running in mapreduce mode or local mode.

You can specify ',' in PigStorage Class to read CSV file.
Query looks like :
grunt> inputfile= load '/training/pig/datetemp.txt' using PigStorage(',') As (EventID: chararray,eventdate: chararray,count:int);
grunt> dump inputfile;
And make sure that you have file '/training/pig/datetemp.txt' on HDFS.
To test run : hadoop fs -ls /training/pig/datetemp.txt

Hadoop MapReduce - Pig/Cassandra - Unable to create input splits

I'm trying to run a MapReduce Job with Pig and Cassandra and I always get the error:
