[jira] [Commented] (FLINK-3147) HadoopOutputFormatBase should expose mutexes for subclasses

    [ https://issues.apache.org/jira/browse/FLINK-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047188#comment-15047188 ] 

Chesnay Schepler commented on FLINK-3147:
-----------------------------------------

sounds like a good idea, and making the locks protected should solve this issue.

does anyone have any concerns over this?

> While adopting PhoenixOutputFormat to a streaming job, I find that the implementation of {{HadoopOutputFormatBase#close}} is not relevant when there's no temp file to move. However, subclasses cannot effectively override implementation because {{CLOSE_MUTEX}} is marked private.
