Description

Change it so instead of hbase.rootdir looking like this:

drwxr-xr-x   5 stack  staff  170 Aug  5 14:43 .data
-rw-r--r--   1 stack  staff   12 Aug  5 14:43 .hbase.id.crc
-rw-r--r--   1 stack  staff   12 Aug  5 14:43 .hbase.version.crc
drwxr-xr-x   3 stack  staff  102 Aug  5 14:43 .logs
drwxr-xr-x   2 stack  staff   68 Aug  5 14:43 .oldlogs
drwxr-xr-x   3 stack  staff  102 Aug  5 14:43 .tmp
-rwxrwxrwx   1 stack  staff   42 Aug  5 14:43 hbase.id
-rwxrwxrwx   1 stack  staff    7 Aug  5 14:43 hbase.version

It looks like this:

drwxr-xr-x   5 stack  staff  170 Aug  5 14:43 data
-rw-r--r--   1 stack  staff   12 Aug  5 14:43 .hbase.id.crc
-rw-r--r--   1 stack  staff   12 Aug  5 14:43 .hbase.version.crc
drwxr-xr-x   3 stack  staff  102 Aug  5 14:43 logs
drwxr-xr-x   2 stack  staff   68 Aug  5 14:43 oldlogs
drwxr-xr-x   3 stack  staff  102 Aug  5 14:43 tmp
-rwxrwxrwx   1 stack  staff   42 Aug  5 14:43 hbase.id
-rwxrwxrwx   1 stack  staff    7 Aug  5 14:43 hbase.version

Also removes any ROOT dir if it is present.
