Thank you @Matt Andruff for your reply. I resolved the issue. I had another .jar in the /lib directory containing the same code but with another file name. I'm not sure how it does affect the execution of the job. But after removing it every thing works fine, for now at least.

Okay, I found a workaround, I added: -Duser.timezone=GMT which changes the the JVM timezon. The final Flume-ng command will be as following: flume-ng agent --conf-file spool1.properties --name agent1 --conf $FLUME_HOME/conf -Duser.timezone=GMT The needed directory for the oozie coordiantor is now being created.

Okay, I installed the NodeManger on the 3 remaining nodes and I have now all the nodes active.

Have you read the documentation on HBaseStorage from the Apache Pig website? http://pig.apache.org/docs/r0.15.0/func.html#HBaseStorage You should be able to just not specify the column family the the columns definition (e.g. a colon with no text before it). If this doesn't work, the parsing logic probably needs to be updated.

Depends what you plan to do. - Aggregation queries and analytical reports then Hive ( simple jdbc connection is supported by BIRT and Pentaho and you can also make servlets with jdbc pools the whole shebang ) - Selecting one record at a time ( like a dashboard that shows the data of one customer Hbase with REST api from javascript might work Hbase with java api from a servlet if you prefer SQL Apache Phoenix is a cool SQL layer on top of HBase https://phoenix.apache.org/ - Interactive reports on thousands to millions of records ( not billions ) Apache Phoenix, it provides some good enhancements on base HBase from a performance perspective for anything that touches more than a row. You can also do Joins aggregations etc. pp. ( If you want HBase but have kerberos setup have a look at Knox its a SSL capable proxy that strips away the Kerberos requirement and replaces it with a normal web authentication setting for the hbase API )

@Neeraj Sabharwal Even in 0.11 it still exist .. see my answer below.

That solved the problem but the Map job stacked, and even after killing it the Yarn container still exists I had to kill it manually. i'll be back to this shortly.

@Zaher Mahdhi I agree, can you please post this as a new question and provide steps to reproduce the problem.
