Sean Busbey commented on HBASE-20597:
-------------------------------------
bookeeper jobs were stomping on system resources last week, though I don't know
if that's specifically what caused process killing here.
> Use a lock to serialize access to a shared reference to ZooKeeperWatcher in

> The code that closes down a ZKW that fails to initialize when attempting to
> connect to the remote cluster is not MT safe and can in theory leak
> ZooKeeperWatcher instances. The allocation of a new ZKW and store to the
> reference is not atomic. Might have concurrent allocations with only one
> winning store, leading to leaked ZKW instances.
