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 — Hitesh On Nov 18, 2015, at 8:58 AM, Brian Jeltema <[email protected]> wrote: > 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.
