Description

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]"
