Subject tez failure after upgrade
Date Wed, 18 Nov 2015 16:58:37 GMT
On completion of a rolling upgrade to HDP 2.3, tez failed it’s service check with:

15/11/18 11:44:49 INFO client.DAGClientImpl: DAG completed. FinalState=FAILED
15/11/18 11:44:49 INFO examples.OrderedWordCount: DAG diagnostics: [Incompatible versions
found, clientVersion=, AMVersion=]

The clientVersion is the version after the upgrade, but the AMVersion is the version before
the upgrade.
Does anyone know what might cause this?
