Review request for hive, Marton Bod and Peter Vary.
Bugs: HIVE-23293
https://issues.apache.org/jira/browse/HIVE-23293
Repository: hive-git
Description
-------
With a new lock type (EXCL_WRITE) for INSERT_OVERWRITE, SHARED_READ does not
have to wait for any lock - it can fails fast for a pending EXCLUSIVE, because
even if there is an EXCL_WRITE or SHARED_WRITE pending, there's no semantic
reason to wait for them.
