--------------------------------------------
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.
