Scanner is jumping a full cache of rows
---------------------------------------

                 Key: HBASE-1891
                 URL: https://issues.apache.org/jira/browse/HBASE-1891
             Project: Hadoop HBase
          Issue Type: Bug
          Components: client
            Reporter: Zheng Shao


I ran my program multiple times and this is happening almost all the time.

Basically, the ResultScanner is skipping a full cache of rows. I set my caching size to 1000, and when I expect to see row 60000 it gave me 60999.

My code (will attach here) is creating a new table with a single column family and qualifier, and then write 1 million rows with ascending keys, then immediately read them back to verify.


The HBase code is from:
http://svn.apache.org/repos/asf/hadoop/hbase/trunk at
Exported revision 821973.
