Subject [jira] Created: (HBASE-524) Problems with getFull
Date Mon, 17 Mar 2008 20:16:25 GMT
Problems with getFull
---------------------

                 Key: HBASE-524
                 URL: https://issues.apache.org/jira/browse/HBASE-524
             Project: Hadoop HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 0.1.0, 0.2.0
            Reporter: Bryan Duxbury
            Assignee: Bryan Duxbury
            Priority: Critical


There are some issues with the implementation of getFull in HStore. 

 * If the loop encounters a deleted cell, it stops iterating. This correctly handles deletes,
but then accidentally masks away any cells of different qualifiers that would come afterward
 * Since the mapfiles are search oldest to newest, and the results map is only updated when
there isn't already a value in the results map for for the cell we're currently looking at,
older values actually take precedence over newer ones. This may be fixed by simply reversing
the order of mapfiles traversed to newest to oldest.
