[jira] Commented: (HIVE-1591) Lock the database also as part of
locking a table/partition
Posted by "John Sichi (JIRA)" <ji...@apache.org>.

John Sichi commented on HIVE-1591:
----------------------------------
I applied this patch and tried the following scenario.
Client 1: insert overwrite table pokes2 select * from pokes;
Client 2: show locks;
Client 2 is getting an ArrayIndexOutOfBoundsException: 1.
Without the patch, show locks works fine.
Besides addressing this issue, two other items:
* the cause of the exception is getting swallowed, so it never makes it to hive.log, due to the code below in DDLTask.showLocks. It should be passing e along as the cause argument to the 2-arg HiveException constructor so that there will be a "Caused By" in the stack dump.
} catch (Exception e) {
throw new HiveException(e.toString());
}
* we really need tests for actual concurrency

Once https://issues.apache.org/jira/browse/HIVE-1590 is fixed, this will automatically enable locking.
