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.
