[jira] [Created] (HBASE-15432) TableInputFormat - support multiple column families scan

nirav patel created HBASE-15432:
-----------------------------------

             Summary: TableInputFormat - support multiple column families scan
                 Key: HBASE-15432
                 URL: https://issues.apache.org/jira/browse/HBASE-15432
             Project: HBase
          Issue Type: New Feature
    Affects Versions: 0.98.16.1, 0.98.16, 2.0.0
            Reporter: nirav patel


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.
