Hi, we use a script to take on a regular basis snapshot's and delete old one's.
We recognizes that the web interface of the hbase master was not working any more becaues of too many open files. The master reaches his number of open file limit of 32768 When I run lsof I saw that there where a lot of TCP CLOSE_WAIT handles open with the regionserver as target. On the regionserver there is just one connection to the hbase master. I can see that the count of the CLOSE_WAIT handles grow each time i take a snapshot. When i delete on nothing changes. Each time i take a snapshot there are 20 - 30 new CLOSE_WAIT handles. Why does the master do not close the handles? Is there a parameter with a timeout we can use? We use hbase 0.94.2-cdh4.2.0. Regards Hansi
