--------------------------------------

             Summary: random high ports not reported properly in the UI
                 Key: HBASE-23551
                 URL: https://issues.apache.org/jira/browse/HBASE-23551
             Project: HBase
          Issue Type: Bug
          Components: master, regionserver
    Affects Versions: 2.2.2
            Reporter: Allan Espinosa


We want to run HBase on kubernetes and want to investigate hostNetworking for performance and host purposes. We basically set hbase.*.port,hbase.*.info.port=0 in our hbase-site.xml .  This will allow us to skip kubernetes networking since hbase-related services will bind to random high ports.

 

We encountered the following bugs in the HBase UI

Active HBase Master:
 * Links to Backup masters points to http://<backup-container-host>:<rpc.port> instead of http://<backup-container-host>:<http.info.port>. The http://<backup-container-host>:<rpc.port> endpoint responds with a proper HTTP 404 from the Jetty instance in the backup master process

Backup HBase master
 * Links to Active Master points to http://<backup-container-host>:<rpc.port> instead of http://<backup-container-host>:<http.info.port>. The http://<backup-container-host>:<rpc.port> endpoint responds with a proper HTTP 404 from the Jetty instance in the backup master process

Regionservers
 * Regionserver running in the same host network as the active hbase master can register
 * Regionserver on different hosts (using host networking) connects to a different RPC port in the active HBase master. I can’t figure out which port is this yet.
