             Summary: Address already in use Should shutdown the datanode with FATAL log and point out the port and configure key
                 Key: HDDS-3498
                 URL: https://issues.apache.org/jira/browse/HDDS-3498
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
    Affects Versions: 0.6.0
            Reporter: maobaolong


Now, the datanode process cannot work because the port is in use, but the process still live.

Further more, i guess the in use port is 9861, but it isn't, after look the source code, i find it is the `dfs.container.ipc`, default port is 9859, this port should appear with the following exception. I think this error should be in FATAL level, and we can terminate the datanode process.
