> *HDP 2.2 using versioned RPMs*
> When Ambari installs Hive, it copies any file that matches /usr/hdp/current/tez-client/lib/tez*.tar.gz
file to hdfs:///apps/tez/tez.tar.gz
> (Aside: it also ends up copying other tez-* files that it shouldn't because they are
not needed, and already zipped in the tar.gz file)
> The problem is that during a rolling upgrade, currently running jobs still needs to reference
the same jar files as when they were created.
> Today, Hive's install_jars.py and params.py route /usr/hdp/current/tez-client/lib/tez*.tar.gz
=> tez.tar.gz
> Instead, it should preserve the version number when copying to HDFS.
> Further, when tez.py generates the tez-site.xml file, it should replace the value of
the tez.lib.uris parameter to include the rpm version number in the value, e.g., hdfs:////apps/tez/tez-0.6.0.2.2.0.0-887.tar.gz
