Todd Lipcon commented on HBASE-2492:
------------------------------------
HDFS-941 is the connection reuse one. I've backported it to hdfs 0.20 but was
seeing exceptions under load, so I put it aside. I may take it back up again
some time in May.
> "BindException: Cannot assign requested address" because all descriptors
> occupied in TIME_WAIT when random reading
