[jira] [Commented] (APEXMALHAR-2224) GenericFileOutputOperator rotateCall fails if no data is written to the file

    [ https://issues.apache.org/jira/browse/APEXMALHAR-2224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15470073#comment-15470073 ] 

Yogi Devendra commented on APEXMALHAR-2224:
-------------------------------------------

One possible solution could be:
check for currentPartTupleCount in GenericFileOutputOperator.rotateCall. If it is zero then return without rotating.
