--------------------------------------------
Summary: PartitionManagementTask should not modify DN configs to
avoid closing persistence manager
Key: HIVE-21103
URL: https://issues.apache.org/jira/browse/HIVE-21103
Project: Hive
Issue Type: Bug
Components: Standalone Metastore
Affects Versions: 4.0.0
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
HIVE-20707 added automatic partition management which uses thread pools to run
parallel msck repair. It also modifies datanucleus connection pool size to
avoid explosion of connections to backend database. But object store closes the
persistence manager when it detects a change in datanuclues or jdo configs. So
when PartitionManagementTask is running and when HS2 tries to connect to
metastore HS2 will get persistence manager close exception.
