Failed binding http info server to port: 60030

mtowse — Fri, 16 Sep 2022 09:21:08 GMT

Hi,

In Cloudera Manager one of our HBase region servers won't start. We get the following message in the logs but can't figure out why it's just this region server and no others and what it is that's blocking it.

Has anyone seen this before? It was working ok but over the weekend seems to have stopped.

org.apache.hadoop.hbase.regionserver.HRegionServer Failed binding http info server to port: 60030

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

Thanks

Mark

Port numbers larger than 32765 (ephemeral ports) can be in use at any
time. It is possible another process is holding the port.

This should tell you the PID that holds the port. That should help
decide next steps
# netstat -nap | grep 60030

Thanks for the reply GautamG

My colleague has a resolved this by restarting all the services on the machine. I had tried just restarting HBase but that hadn't worked.

Cheers
