When I create explicit lock using lock table tablename partition(partitionname) exclusive. It acquires lock as expected. I have a requirement to release the lock if hive connection with process who created the lock dies .How to achieve this? In current situation lock is released only explicitly by calling unlcok table tbalenme partition(). Requirement is to handle the process which acquires a lock and gets killed because of any reason before calling unlock. While using TxnMgr org.apache.hadoop.hive.ql.lockmgr.DbTxnManager for handling transaction timeout it did n't allow explicit locking and threw below exception FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Current transaction manager does not support explicit lock requests. Transaction manager: org.apache.hadoop.hive.ql.lockmgr.DbTxnManager
