Subject [jira] [Commented] (TEZ-1635) Dag gets stuck intermittently
Date Sun, 05 Oct 2014 03:43:33 GMT

    [ https://issues.apache.org/jira/browse/TEZ-1635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14159415#comment-14159415

Bikas Saha commented on TEZ-1635:
---------------------------------

[~hagleitn] Please provide the info I asked earlier in a comment. We need to know if Hive
never sent the InputDataInformationEvents or they were sent but Tez lost them. From what I
saw in the logs, Map5 tasks have 2 inputs but was sent only 1 event. At least 2 should have
been sent.
bq. Maybe you can put more logs in the custom vertex manager for Map 5 to verify if the split
events for the inputs are being generated and sent whenever the job hangs.
