--------------------------------------
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.
