Add the below in the shell action or put it in /etc/oozie/conf/oozie-site.xml and restart the oozie server. This will increase the console output data that can be captured as part of the shell action tag <capture-output/>. The default is 2048 which is Max size in characters for output data.

 <configuration>             
  <property>
    <name>oozie.action.max.output.data</name>
    <value>8192</value>
  </property>        
</configuration>

The <capture-output/> is not required if you not using the console output from the shell action for any decisions in next action. Try just by removing the tag <capture-output/> if not required.

  • Sorry Forgot to mention, I need "<capture-output/>" for next action. One more thing, even if i increase (oozie.action.max.output.data) size, the file will huge size. So it will make problem again.

  • What do you mean by file is huge? it does not depend on file size you are using in hdfs put command. It captures the characters that gets printed on the console when you execute your shell script.

  • Try executing your shell script without oozie from terminal and then see how much characters gets printed on the terminal console. Increase the oozie.action.max.output.data size more than that. It will work

  • So you are saying this command "hdfs dfs -put -f file hdfspath" generates output that exceeds 2kb right? I printed that output and its generating 18kb size of logs.

  • If i run that from terminal without oozie, its not generating any log. When i use oozie shell action only it produces output logs
