Summary: TxnHandler.enqueueLockWithRetry() should now write TXN_COMPONENTS if partName=null and table is partitioned
Key: HIVE-17821
URL: https://issues.apache.org/jira/browse/HIVE-17821
Project: Hive
Issue Type: Bug
Components: Transactions
Reporter: Eugene Koifman
Assignee: Eugene Koifman
Priority: Critical
LM may acquire read locks on the table when writing a partition.
There is no need to make an entry for the table if we know it's partitioned since any I/U/D must affect a partition (or set of).
Pass isPartitioned() in LockComponent/LockRequest or look up in TxnHandler
