Hbase regionserver unable to connect to master

Question

I am using Hbase{ hbase-0.94.3 } and hadoop{ hbase-0.94.3 } on a cluster of six nodes. The operating system installed on my machine fedora. For Hbase I am having one master node and 6 regionserver.

But the strange issue, is that my Hbase regionservers are not able to connect to the master. Only the region server which runs on the same machine as master is able to connect to the master.

For 5 out of 6 region servers I am getting the following error:

I am getting the following error message: 2013-02-28 19:50:26,609 INFO org.apache.hadoop.hbase.regionserver.HRegionServer: Attempting connect to Master server at serv11.mycompany.com,60000,1362102564107 2013-02-28 19:51:26,657 WARN org.apache.hadoop.hbase.regionserver.HRegionServer: Unable to connect to master. Retrying. Error was: java.net.ConnectException: Connection refused at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) ....

Any help on this is highly appreciated.

Answer 1

Looks like some problem with the internal/external ip addr. I used the external IP addr and then most of things got solved.

Dont know much about networking but closing this question, as the issue is resolved.
