Mikhail Bautin commented on HIVE-3913:
--------------------------------------
[~ashutoshc]: thanks for pointing this out. I took a look at HIVE-3537, and I
think this is a much simpler fix for a situation that I observed when the
client attempts to acquire a lock, but the ZK connection is closed for some
reason and no reconnection is attempted.
