> 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: Minor
>
> 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
