------------------------------
Summary: Hive restart fails to restart MySQL after Ambari upgrade
against IOP 4.2.5
Key: AMBARI-21555
URL: https://issues.apache.org/jira/browse/AMBARI-21555
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.5.2
Reporter: Di Li
Assignee: Di Li
Fix For: 2.5.2
IOP uses MariaDB instead of MySQL when a cluster is on RedHat 7. HDP 2.6/Ambari
2.5.2 is yet to support MariaDB. A special flag is introduced to switch daemon
type for migrated clusters. Currently the flag is added during EU to handle
both IOP 4.2 and 4.2.5. We also need this flag to be added during Ambari
upgrade for IOP 4.2.5 to restart MySQL ( IOP 4.2 is self-contained, thus not
need this flag for restarting MySQL)
