HBase MasterNotRunningException
Jilani Shaik 2012-08-30, 13:30
Hi,

I have installed and configured  Hadoop(hadoop-1.0.3) and
HBase(hbase-0.94.1) in a single Fedora linux box, where HBase
as pseudo cluster setup.

I am able to connect the HBase suing shell from console and able to create
and scan table. But when I tried to contact the same using java application
I am not able to connect the HBase.

Output of "jps" as follows
16872 HRegionServer
16603 HQuorumPeer
15821 DataNode
16047 JobTracker
16667 HMaster
17984 Jps
15680 NameNode
15959 SecondaryNameNode
16179 TaskTracker

The error log for zoo keeper of HBase is as follows
