I am new to hadoop and hadoop streaming so this error is probably something obvious that I miss.
I run an inline awk mapper command and it works fine.
hadoop jar $HADOOP_HOME/contrib/streaming/hadoop-streaming-1.0.3.jar -input input -output output -mapper "/usr/bin/awk -F'\t' '\$1==\"and\"'" -reducer NONE
However, when I put the awk command to a file and run it. I got Java IOException on all machines in the cluster.
hadoop jar $HADOOP_HOME/contrib/streaming/hadoop-streaming-1.0.3.jar -input one_to_one/part* -output 4 -mapper test.sh -reducer NONE -file test.sh
test.sh
/usr/bin/awk -F '\t' '(NR == 1) {print NR,OFS,$0;}'

I'm using wikipediaminer and Hadoop in my project.
When I run the following code in Linux terminal:
hadoop jar wikipedia-miner-hadoop.jar org.wikipedia.miner.extraction.DumpExtractor input/dump.xml input/languages.xml en input/en-sent.bin output
I got this error:

Where <input dir> is a directory with many avro files.

How can this issue be resolved ?
It took a while, but I found the solution here.
Prepending HADOOP_CLIENT_OPTS="-Xmx1024M" to the command solves the problem.
The final commandline is:
HADOOP_CLIENT_OPTS="-Xmx1024M" hadoop jar hadoop-streaming.jar -D stream.tmpdir=/tmp -input "<input dir>" -output "<output dir>" -mapper "grep 20151026" -reducer "wc -l"

Here is the code I'm running
raw_data = LOAD '/data/QCLCD201211/201211hourly.txt' USING PigStorage(',');
weather_data = FOREACH raw_data GENERATE $1, $10;
ranked_data = RANK weather_data;
final_data = FILTER ranked_data BY $0 IS NOT NULL;
STORE final_data INTO 'hbase://weather'
USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('info:date info:temp');
As you can see, I think the error code is not in the pig but something else that I do not understand.
copy pig jar and hbase jar in hadoop
1) COPY THESE FILES TO THE HADOOP LIBRARY.

The command I am using is :
./elastic-mapreduce --jobflow j-12345678 --jar /home/hadoop/lib/emr-s3distcp-1.0.jar --args '--src,s3n://my-bucket/data/,--dest,hdfs:///data/in,--srcPattern,xyz01-1-1*ped*' --step-name "Copy input files to HDFS" --wait-for-steps
I tried to run the sample word-count job, to check if there is any issue with HDFS, but it ran fine.
Can anyone please help me with this? If any more info is needed, please let me know and I will update the description.
Usually its the --srcPattern '<regex>' argument. You can also use hadoop fs -cp s3://src/file1.something /my/output/path/ to test for 1 file and modify your regex. Also starting with .* any char-0 or more times, should relax the matching.
It would be great to know if regex non-matches get logged and where.
Using Mahout seq2sparse command, I manage to successfully create the following folders in HDFS
df-count
dictionary.file-0
frequency.file-0
tf-vectors
tfidf-vectors
tokenized-documents
wordcount
After that when I run the trainnb command with the following syntax
mahout trainnb -i tweet-vectors -el -li labelindex -o model -ow -c
I get the following error. Does anyone know resolution for the same?

It seems mahout cannot see the file /user/hhhh/tweet-vectors/df-count in HDFS.
First, try hadoop dfs -ls /user/hhhh/tweet-vectors/df-count to verify the file exists.
If it doesn't exist, there's your problem. If it does exist, check if it is a file or a directory. mahout seems to be looking for a file, not a directory.
If is exists and it is a file, then verify that mahout is connecting to the same hadoop namenode instance where the file is stored.
