Description

When testing HBASE-21401, we found that two UT related to RowIndexSeekerV1 always failed [1]. because RowIndexSeekerV1 may return cell with extra two \x00\x00 bytes which has no tags..

I plan to fix this bug in HBASE-21401, but seems the checkKeyValueBytes need more performance evaluation, as Apache9 & stack comment. I opened issue HBASE-21459 to address it.

So, let me fix this bug firstly (Also will provide a seperate UT for this).
