https://community.cloudera.com/t5/Support-Questions/How-to-identify-the-user-who-has-acquired-table-lock-in-Hive/m-p/226748#M188608 <P>I had a scenario where a Sqoop ingestion query failed on Hive table due to table lock issue. Does Hive maintain lock history? Is there any way to check which user has acquired this lock after lock is released. From the log I am getting below message.</P><PRE>FAILED: Error in acquiring locks: Lock acquisition for LockRequest(component:[LockComponent(type:EXCLUSIVE, level:TABLE, dbname:db_name, tablename:table_name, operationType:NO_TXN)], txnid:0, user:user_name, hostname:myhost.org.com, agentInfo:user_20171218230532_32d0dac8-17d9-4f1c-af90-be7e6f8e0358) timed out after 5502640ms.
