Perfect..saved my life!!! For cloudera user's like me, if you are using quickstart vm then issue the below command to get it working cd <zeppelin_dir> ./bin/zeppelin-daemon.sh stop sudo chown -R cloudera:cloudera webapps ./bin/zeppelin-daemon.sh start

If I create a plain target table would I be able to alter the table later? What I mean is, create a plain table and then alter the table to add the buckets? If yes, how?

I am trying to create a table with Bucketing from another table using select but it fails. Here is my query create table tmp CLUSTERED BY (key) INTO 256 BUCKETS as select * from link_table limit 10; And I get the below error FAILED: SemanticException [Error 10068]: CREATE-TABLE-AS-SELECT does not support partitioning in the target table link_table is already bucketed. I have also set the property to enforce bucketing. I am not sure if bucketing is supported with CTAS. Is there a way I can get this working?

"Issue Fixed" I talked with my DevOps later and found that the classpath for Java was not set in few datanodes in the Cluster. This was stopping the shell action to invoke the JVM at those datanodes. After fixing the Classpath, the job ran successfully

That is carriage return from the log while copying the content. I have created the JAVA_PATH accordingly.

I am running a java program from a shell script through Oozie and I get the below error java: command not found
When I run the shell script from the edge node I do not find any issues and the java class runs without any error and I get the desired output also. However it is the oozie job that fails to run the java command. All other actions in oozie are executed porperly but when it encounters the java line, it throws the afore said error. I understand that all the nodes in the Hadoop cluster will have Java installed, then why do I get this error? Below is the java command that I have in my shell script ...

java -cp $LOCAL_DIR/libs/integration-tools.jar com.audit.reporting.GenerateExcelReport $LOCAL_DIR/input.txt $LOCAL_DIR/

After a tireless research on the internet I was able to crack the solution for the issue.
I have added a configuration to use the metastore server for the Hive job and it worked.
Here is what I did to the Hive action. ....
<hive xmlns='uri:oozie:hive-action:0.2'>
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<configuration>
<property>
<name>hive.metastore.uris</name>
<value>thrift://10.155.1.63:9083</value>
</property>
</configuration>
<script>${dir}/gsrlQery.hql</script>
<param>OutputDir=${jobOutput}</param>
</hive>
.... Note: replace the hive metatore ip accordingly if you are trying to fix a similar problem. To get the metastore details check the hive-site.xml file located in /etc/hive/conf dir. Credit: MapR
