Subject Re: tez failure after upgrade
Date Wed, 18 Nov 2015 18:08:44 GMT
I was running Ambari 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.

easily fixed by deleting the wrong tarball in HDFS under the the 2.3.2 version dir and replacing
it with the correct one.
