Review request for Ambari, Andrew Onischuk, Jonathan Hurley, Sumit Mohanty, and Sid Wagle.

Bugs: AMBARI-11039

Repository: ambari


Summary: Customers with Ambari 2.0.0 that performed an RU from say HDP to
will not have the correct version of tez.tar.gz uploaded to HDFS.

Details: During HiveServer2 Restart in RU, it copied to wrong tez.tar.gz to HDFS (because
the symlink in /usr/hdp/current/tez is still pointing to the old version at this time).
The reason why Service Checks pass is that these tarballs are compatible enough with each
other. However, during RU from 2.2.* to 2.3.*, this is likely to break.

Impact: Applications that depend on this tarball (Pig, Tez, Hive) will be running with older
classes. This does not appear to be breaking in HDP 2.2, otherwise customers would have reported
it. However, it certainly does have to be fixed in Ambari 2.1.0 because tez.tar.gz has more
significant changes and does encounter a version incompatibility error.





Created a 3-node CentOS 6 cluster
Installed Ambari 2.0.1
Copied scripts
Installed HDP GA with HDFS, YARN, MR, Hive, ZK, Tez, Pig
Added NameNode HA
Performed an RU to HDP, which copied the correct tarball to HDFS.

Python unit tests passed,
