> 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.
