[jira] [Commented] (YARN-6630) Container worker dir could not
recover when NM restart
[ https://issues.apache.org/jira/browse/YARN-6630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16022223#comment-16022223 ]
Feng Yuan commented on YARN-6630:
---------------------------------
IMO,by default when nm starts it will clear all workdirs, if we should skip some workdirs those container is recovering?
Any ideas?
