---------------------------------------
Summary: Add option to enable connectionLeak detection for Hikari
datasource
Key: HIVE-25482
URL: https://issues.apache.org/jira/browse/HIVE-25482
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
There are corner cases where we observed connection leaks to DB.
It will be good to add an option to provide connection leak timeout parameter
in HikariCPDataSourceProvider.
[https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/datasource/HikariCPDataSourceProvider.java#L69]
e.g following should help Hikari to warn about connection leak, when a
connection is not returned to the pool for 1 hour.

config.setLeakDetectionThreshold(3600*1000); {noformat}
