Subject [jira] Created: (HBASE-3093) DeleteColumns deletes alphabetical next columns when using timestamp 0
Date Fri, 08 Oct 2010 08:12:33 GMT
DeleteColumns deletes alphabetical next columns when using timestamp 0
----------------------------------------------------------------------

                 Key: HBASE-3093
                 URL: https://issues.apache.org/jira/browse/HBASE-3093
             Project: HBase
          Issue Type: Bug
            Reporter: Evert Arckens


When calling Delete.deleteColumns to delete (all versions of) a column, the columns with a
qualifier that is alphabetical higher than the deleted column are deleted as well when the
cells have timestamp 0.
When the cells have a timestamp higher than 0 this is not the case.

The test case DeleteColumnsTest (tested against HBase 0.89.0-r1004203-3076) contains a scenario
showing this behaviour :
- put values in 3 columns (A, B and C) of the same column family at timestamp 0.
- delete all versions of column B (using Delete.deleteColumns() )
- read columns A and C
- result : for column A a result is given, for column C not (the alphabetical order is in
play here!)
