Subject: Re: tez failure after upgrade

I was running Ambari 2.1.2.1. The problem was that the value of tez.lib.uris 
was not updated by the
rolling upgrade. Updating it and restarting the tez clients fixed the problem. 
Thanks.

Hello Brian,

What version of Ambari are you running? I believe there were bugs in earlier 
versions that uploaded the wrong version of the Tez tarball to HDFS during an 
upgrade.

You can check this by comparing the tez tarball on HDFS ( pointed to by 
tez.lib.uris in tez-site.xml ) to the tez tarball in the respective version of 
the Tez rpm. This can be easily fixed by deleting the wrong tarball in HDFS 
under the the 2.3.2 version dir and replacing it with the correct one.

This may also impact the MapReduce tarball too but MR jobs do not fail as they 
don't have a compatibility check in place.

thanks

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=0.7.0.2.3.2.0-2950, 
AMVersion=0.5.2.2.2.8.0-3150]

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

Thanks
Brian
