Hi , I was able to add region server dynamically in running cluster . But this happens only when hostname of new node is resolved to IP by running cluster. Now to achieve this I have to add new node IP and hostname in /etc/hosts file and rebooted the machine. Restarted the cluster and added node dynamically.
Now since currently in Hbase it resolves only hostname and not IP is a drawback I see because if I want to add any regionserver dynamically it must be present in my /etc/hosts file on each node and this is not always possible. Any suggesstions if it can be fixed?

I updated conf/regionserver file and added IP (not hostname) of new node and started regionserver daemon on the new node. It is started fine but on Hbase webUI it doesnot shows the new regionserver added. As far as I know Hbase resolve the hostname of the nodes. Now if I add hostname to conf/regionserver file then I will also need to update /etc/host and reboot the machines otherwise it will give" unkown host exception ". Am I missing something ? -Stuti ________________________________ ::DISCLAIMER:: ----------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
