[jira] [Created] (HBASE-20928) binarySearch function in RowIndexSeekerV1 is buggy

saurabh singh created HBASE-20928:
-------------------------------------

             Summary: binarySearch function in RowIndexSeekerV1 is buggy
                 Key: HBASE-20928
                 URL: https://issues.apache.org/jira/browse/HBASE-20928
             Project: HBase
          Issue Type: Bug
          Components: io
            Reporter: saurabh singh


There are couple of issues in the function:
 * {{>>>}} operator would mess the values if {{low}} + {{high}} end up being negative. This shouldn't happen but I don't see anything to prevent this from happening.

 * The code fails around boundary values of {{low}} and {{high}}. This is a well known binary search catch. [https://ai.googleblog.com/2006/06/extra-extra-read-all-about-it-nearly.html]
