      Description

      The Get operation only supports setting the max version for all column families. But different column families may have different versions data, and users may want to get data with different versions from different column families in a single Get operation.

      Though, we can translate this kind of Get to multi single-column-family Gets, these Gets are sequential in regionserver and have different mvcc.

      Comments and suggestions are welcomed. Thx

        Sounds reasonable to me.

        I'd prefer to see multiget use a single mvcc and be executed more like doBatchOp. See HBASE-11056. I haven't pursued Sergey's reference, however, so I don't know how this will change after HBASE-10070.

        Thanks, Nick Dimiduk.
        Agree, it's a more generic method. I will pay a attention to that issue.
