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.
