[jira] Created: (HDFS-1055) Improve thread naming for DataXceivers

Improve thread naming for DataXceivers
--------------------------------------

                 Key: HDFS-1055
                 URL: https://issues.apache.org/jira/browse/HDFS-1055
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon


The DataXceiver threads are named using the default Daemon naming, which is Runnable.toString(). Currently this isn't implemented, so threads have names like org.apache.hadoop.hdfs.server.datanode.DataXceiver@579c9a6b. It would be very handy for debugging (and even ops maybe) to have a better name like "DataXceiver for client 1.2.3.4 [reading block_234254242]"
