Subject Re: HBase establishes session with ZooKeeper and close the session immediately
Date Wed, 24 Sep 2014 02:11:23 GMT
It seems to be related to replication. When I disable the replication from
the other clusters, the problem doesn't occur again. And I print the DEBUG
log to find some abnormal result. I don't think we should get the response
of "value=-2209236057317107828" when scan the META table.
