[jira] [Commented] (TEZ-519) Misleading stack trace when using
sessions
[ https://issues.apache.org/jira/browse/TEZ-519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13780302#comment-13780302 ]
Bikas Saha commented on TEZ-519:
--------------------------------
YARN also shows the app as KILLED. We should avoid having too many spurious KILLED/FAILED sessions. This is with latest synced code.
