Subject [jira] [Commented] (HIVE-10500) Repeated deadlocks in underlying RDBMS cause transaction or lock failure
Date Tue, 28 Apr 2015 22:29:06 GMT

Alan Gates commented on HIVE-10500:
-----------------------------------

[~ekoifman], I didn't change the log level as that was already that way.  This patch doesn't
make it worse.  If we find it to be a problem we can change it separately.
