Description
$ /usr/sbin/lsof -i TCP:50010 | grep -c CLOSE_WAIT
4471
It is better if everything runs normal.
However, from time to time there are some "DataStreamer Exception: java.net.SocketTimeoutException" and "DFSClient.processDatanodeError(2507) | Error Recovery for" can be found from log file and the number of CLOSE_WAIT socket just keep increasing
The CLOSE_WAIT handles may remain for hours and days; then "Too many open file" some day.
