Eugene Koifman created HIVE-18332:
-------------------------------------
Summary: Lock acquisition timeout should show what blocked it
Key: HIVE-18332
URL: https://issues.apache.org/jira/browse/HIVE-18332
Project: Hive
Issue Type: Improvement
Components: Transactions
Affects Versions: 1.0.0
Reporter: Eugene Koifman
For example
{noformat}
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. LockResponse(lockid:28622126, state:WAITING)
{noformat}
SHOW LOCKS can display what the failed lock was blocked on.
Should try to include it in the error above since Show Locks info will
disappear once the "blocked on" lock is released.
