Hi Stack, yes . I can still see the column family. we ran the following command too:
fs -dus /hbase/<table name>/<region hash>/<cf that was deleted> and it returned a large value which means that the space has not been reclaimed. The hbase version we are running is 0.94.1. is there a manual way to force reclaim the space? regards, Prem On Tue, Aug 7, 2012 at 12:52 PM, Stack <[email protected]> wrote: > On Tue, Aug 7, 2012 at 7:19 AM, prem yadav <[email protected]> wrote: > > We have a small Hbase cluster on EC2 with 6 region servers.
