> HBase dose not close a dead connection with the datanode.
> This resulting in over 60K CLOSE_WAIT and at some point HBase can not connect to the
datanode because too many mapped sockets from one host to another on the same port.
> The example below is with low CLOSE_WAIT count because we had to restart hbase to solve
the porblem, later in time it will incease to 60-100K sockets on CLOSE_WAIT
