-------------------------------------------
Summary: While doing express upgrade multiple Clients and Services
Failed to start
Key: AMBARI-14293
URL: https://issues.apache.org/jira/browse/AMBARI-14293
Project: Ambari
Issue Type: Bug
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
Attachments: AMBARI-14293.patch
During nightly run over Centos7 express upgrade test cases failed because of
TEZ Client issue.
Restart of Tez Client failed after upgrade because of conf file missing.
After logging on box I found the soft links /etc/tez/conf &
/usr/hdp/current/tez-client/conf pointing in loop to each other.
