> Currently Hbase TableInputFormat class has SCAN_COLUMN_FAMILY and
> SCAN_COLUMNS. SCAN_COLUMN_FAMILY can only scan single column family. If we
> need to scan multiple column families from a table then we must use
> SCAN_COLUMNS where we must provide both columns and column families which is
> not a convenient. Can we have a SCAN_COLUMN_FAMILIES which supports scan of
> multiple column families.
