w/ a default of 32.

> Our cluster lost data.  Made for some interesting scenarios in hbase.  One such was empty
index files (Would get an EOFException when we tried to scan or open region).  HBASE-646 added
checking of data, info, and index files.  Tried to run repair of indexes but was doing it
wrong place and wasn't first removing the broken index so it'd fail.
