Looks like you are loading data in MapR DB not in hbase.But its fine hbase commands are compatible with MarDB. I just a small change in your command and see if that works for you.
hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.columns=HBASE_ROW_KEY,personal:Name,Profession:Position_Title,Profession:Department,personal:Employee_Annual_Salary '-Dimporttsv.separator=,' /tables/emp_salary_new1 /mapr/MapRDev/apps/Datasets/Employee_Details.csv

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
{"_id":{"$oid":"5a1321d5741a2384e802c552"},"reviewerID":"A3HVRXV0LVJN7","asin":"0110400550","reviewerName":"BiancaNicole","helpful":[4,4],"reviewText":"Best phone case ever .

It was in perfect condition as well.","overall":5.0,"summary":"A++++","unixReviewTime":1358035200,"reviewTime":"01 13, 2013","category":"Cell_Phones_and_Accessories","class":1.0}
{"_id":{"$oid":"5a1321d5741a2384e802c557"},"reviewerID":"A1BJGDS0L1IO6I","asin":"0110400550","reviewerName":"cf \"t\"","helpful":[0,3],"reviewText":"ITEM NOT SENT from Blue Top Company in Hong Kong and it's been over two months!

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.

Oozie workflow giving error on Hive job when underlying job completes successfully

Part of self-learning I am exploring Oozie, and I am practicing on Hortonworks Sandbox VM. The problem is that Oozie workflow is getting error and getting killed as a result when underlying job given by the link in Oozie UI shows success.
I have looked at this question and have included
<job-xml>hive-site.xml</job-xml>
in the job description, and have copied hive-site.xml to HDFS to the correct folder but to no avail. Additionally, I have double checked all URLs and everything is right.
I am running the Oozie job from command line. I have no idea where to start debugging or how to get a more detailed error. Following are screenshots:
Oozie Error
Underlying Hive job indicates successful completion.
I do not see the final result as hive table as I am supposed to see.
Following is the log output of the Map task:
<<< Invocation of Hive command completed <<<
Hadoop Job IDs executed by Hive:

<<< Invocation of Main class completed <<<

To find the error check:
Check the "Child Job URLs" check each child job.
Check stdout and stderr
Sometime the error is in the child job and you will need to do some drill down on every one of them.

hadoop Input path does not exist

I am trying to get hadoop set up on my laptop. I have followed a few tutorials on setting up hadoop.
I ran this command:
bin/hdfs dfs -mkdir /user/<username>
If I run it again it says already exists.
I try to run the test jar file with this command:
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar grep input output 'dfs[a-z.]+'
and receive this exception

Failing this attempt. Failing the application.
There is a stack trace the follows this.
I am on a Mac PC.

I use Hadoop 2.7.2, and While following the Official Docs, I also encountered this problem at first.
The reason was that I forgot to follow "Prepare to Start the Hadoop Cluster" chapter.
I solved it by setting JAVA_HOME in etc/hadoop/hadoop-env.sh.

For me, it's because using wrong version JDK with hadoop. I used hadoop 2.6.5. At first, I started hadoop using oracle JDK 1.8.0_131, ran example jar and error occurred. After I used JDK 1.7.0_80, the example works like a charm.
There is a page about HadoopJavaVersions.

Seems to be an error in your dataprocessing chain. This log entry points out that a tuple is null. Just an idea: This can happen, eg when you use customized UDFs, which return Null in some cases.

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! :-)
