Checking if a file exists in HDFS location with size greater than zero, using Oozie

QUESTION

Checking if a file exists in HDFS location with size greater than zero, using Oozie

Asked 2020-Sep-17 at 13:48

I have a Oozie workflow containing a Pig action generating a part-file as output as

/user/wf_user/app_dir/output/part-v003-o000-r-00100

After the Pig action, there is an fs-action which is generating a completion-flag file and moving part-v003-o000-r-00100 to alert_message (for renaming) and then change access permission on the file path /user/wf_user/app_dir/output/alert_message to make the file accessible from subsequent workflow actions.

Thereafter, there is a decision control node to check if the file /user/wf_user/app_dir/output/alert_message exists and is having size greater than zero. Only if the size is non-zero, the alert message will be emailed.

But even though the file exists and is having non-zero size, the decision condition is always returning false, thereby the alert message is never emailed to the notify users.

...

Passed the ${alert_message_file} as a workflow configuration property to get the error resolved. Actually the variable alert_message_file (defined in properties) was not accessible unless it is passed through configuration property through workflow, else there would be "variable could not be resolved" error.

In workflow.xml
