> 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 because 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.
