+ To be used when regions present on hbase:meta, but with no related
+ directories on the file system. Needs hbase:meta
+ to be online. For each table name passed as parameter, performs diff
+ between regions available in hbase:meta and region dirs on the given
+ file system, removing extra regions from meta with no matching directory.
+ An example removing extra regions for tables 'tbl_1' in the default

+ namespace 'n2':
+ $ HBCK2 removeExtraRegionsFromMeta default:tbl_1 n1:tbl_2 n2
