Description

Summary: Customers with Ambari 2.0.0 that performed an RU from say HDP 2.2.0.0 to 2.2.4.2 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.
