      Description

      Yesterday, on our cluster, a region compact() kept crashing at giving this stack trace

      2010-10-25 08:48:28,330 ERROR org.apache.hadoop.hbase.regionserver.CompactSplitThread: Compaction failed for region MailBox_dark_launch_2010_10-04,4b64b600,1286302852538.9183a3b91ebd289bab7724d028cffa69.

      The problem is that we are oveflowing "int" for "bitSize". The number of keys is about 272M, and we are using about 11 bit per key. So, bitSize ends up being > 2G..
