[jira] [Commented] (YARN-4581) thread leak makes RM crash while RM
is recovering
[ https://issues.apache.org/jira/browse/YARN-4581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15093293#comment-15093293 ]
Naganarasimha G R commented on YARN-4581:
-----------------------------------------
Given that AHS(including FileSystemWriter) is already deprecated and planned to be completely removed (YARN-4542), Do we need to work further on this issue ?
