Unable to init HBaseAdmin
Hi,
I have three node HBase cluster that works with HBase CLI. I am able to
login, create, drop tables using HBase CLI.
Hadoop's version is hadoop-0.20.2-cdh3u4 and HBase is hbase-0.90.6-cdh3u4
But when I try to connect via Java client, I am not able to instantiate
HBaseAdmin. Any idea why this would happen?
Here's exception I see in HBase Master logs -
WARN org.apache.hadoop.ipc.HBaseServer: IPC Server listener on 60000:

Yup. That was the reason. I wasn't using cloudera artifacts in my
dependency and there was mismatch in versions.
It all fixed when I started using correct cloudera artifacts in my
application.

Mismatched versions (client and server)?
