--------------------------------------

             Summary: Avoid passing cell to ScanQueryMatcher when optimize SEEK to SKIP
                 Key: HBASE-17958
                 URL: https://issues.apache.org/jira/browse/HBASE-17958
             Project: HBase
          Issue Type: Bug
            Reporter: Guanghao Zhang


{code}
ScanQueryMatcher.MatchCode qcode = matcher.match(cell);
qcode = optimize(qcode, cell);
{code}
The optimize method may change the MatchCode from SEEK_NEXT_COL/SEEK_NEXT_ROW to SKIP. But
it still pass the next cell to ScanQueryMatcher. It will get wrong result when use some filter,
etc. ColumnCountGetFilter. It just count the  columns's number. If pass a same column to this
filter, the count result will be wrong. So we should avoid passing cell to ScanQueryMatcher
when optimize SEEK to SKIP.
