[ https://issues.apache.org/jira/browse/TEZ-3097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15608575#comment-15608575 ]
Jason Lowe commented on TEZ-3097:
---------------------------------
This is still occurring, see https://builds.apache.org/job/PreCommit-TEZ-Build/2061//testReport/org.apache.tez.dag.app.dag.impl/TestCommit/testDAGCommitStartedEventFail_OnDAGSuccess/
Looks like there can sometimes be pending history events after the DAG enters a terminal state.
