             Summary: Seeing INTERNAL_SERVER_ERROR for JDBC queries due to 
connection unavailability
                 Key: LENS-1155
                 URL: https://issues.apache.org/jira/browse/LENS-1155
             Project: Apache Lens
          Issue Type: Bug
          Components: driver-jdbc
            Reporter: Sushil Mohanty
            Assignee: Sushil Mohanty
             Fix For: 2.6


When users that are issuing InMemory Queries, the connection is released back 
to pool only after result set is read completely or after query is purged. 
For InMemory Queries (not persisted by lens server), the query state is changed 
to SUCCESSFUL even before connection is released.
This causes connection pool to throw error for new queries whenever JDBC driver 
is running at almost full load.
