Hbase ConnectionLoss for /hbase/master
Hi Guys,
I trying to run hbase based parser program. Basically the parsed output
written in Hbase table. When I ran my program. tables created some data
also inserted to the table. but not fully table updated.
This Exception seen in console output. I try to find goggling it's gives
try to configure zookeeper session. I correctly
configure hbase.zookeeper.quorum property I mentioned all my zookeeper
machine names.

Since the exception came from zookeeper, please check zookeeper log(s) on
the quorum.
Thanks

Re: Hbase ConnectionLoss for /hbase/master
Posted by Jimmy Xiang <jx...@cloudera.com>.
Is this exception seen in the client side? Was your HBase still running
fine at that moment?
How many connections do you open in your client? Which HBase version is it?
Thanks,
Jimmy
