Hi,
We're using hbase 0.20.5 with cdhb3v2
I got the following exception when starting hbase:
starting master, logging to
/usr/local/hadoop//hbase/logs/hbase-hadoop-master-sjc1-hadoop8.sjc1.carrieriq.com.out
Exception in thread "IPC Client (47) connection to

I only see this in master log:

Can someone shed some light ?
Thanks
