Matt Foley commented on HDFS-2028:

There is an open bug related to lots of port 50010 sockets hanging around in CLOSE_WAIT state:
HDFS-1836 (bug exists in v20 only, was just fixed a couple weeks ago, in v20 branch; patch
pending for v20.205).

Also, not sure of the port number, but also related to excessive open sockets: HDFS-1057 (comment
fixed in trunk, 0.21, 0.20-append.

ESTABLISHED or CLOSE_WAIT status socket connections. And these tcp connections won't be released
unless you quit hive or restart hiveserver.
