> 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.
