ramkrishna.s.vasudevan updated HBASE-13933:
-------------------------------------------
Attachment: HBASE-13933.patch
Just apply this to the TestSeekTo test case and you could see that there is an
exception when the test tries to retrieve the row part from the cell retrieved.
The error is due to the fact that the tagsOffset is wrong and thus the copy
throws IndexOutofBound during Array copy. So this could just happen in a case
where we have tags and would want to read the tags part from a Cell like VC or
ACL.
> DBE's seekBefore with tags corrupts the tag's offset information thus leading
> to incorrect results

> The problem occurs with moveToPrevious() case and incase of tags we copy the
> previous pointer's tag info to the current because already decoded the tags.
> Will check once again before I post other details. I have a test case to
> reproduce the problem. Found this while working with MultibyteBuffers.
