--------------------------------------------

             Summary: RU wrong version of tez.tar.gz uploaded to HDFS
                 Key: AMBARI-11039
                 URL: https://issues.apache.org/jira/browse/AMBARI-11039
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.0.1


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.
