-------------------------------------------
Summary: Rolling Upgrades - hdfs:///apps/tez/tez.tar.gz needs to
be versioned
Key: AMBARI-7825
URL: https://issues.apache.org/jira/browse/AMBARI-7825
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 1.7.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Priority: Blocker
Fix For: 1.7.0
*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
