Unable to start Namenode and HBase- master on Cloudera Manager

Hi folks,

*Caused by: java.net.BindException: Address already in use*

That error in the logs more or less uniquely means that the port is already
being used by some other process. Here is how I tend to check what ports
are being used:

$sudo lsof -P -n | grep LISTEN | grep 60030
java 28283 hbase 312u IPv4 148789875 0t0
TCP *:60030 (LISTEN)

You should check the configuration to figure out what ports HBase is trying
to use, and who they're used by. If it's a different HBase process, then
probably you installed the "hbase-master" package from CDH and it's
starting HBase for you when your machine boots. Turn that off with
"chkconfig" and "service hbase-master stop". If it's some other random
process, you can either kill it or change the port numbers in the CM
configuration screens.

Cheers,
