Subject [jira] Updated: (HADOOP-1045) Code for HBase
Date Fri, 09 Mar 2007 17:15:09 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1045?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jim Kellerman updated HADOOP-1045:
----------------------------------

    Attachment: hbase.patch

- Fix bug that caused a null pointer exception in HRegion.closeAndMerge
- Add detail to exception thrown from HRegion.checkRow
- Change map.seek(); map.next() to map.getClosest() in Hstore.getFull,
  HStore.get
- Add constructor and suite() to TestHRegion
- Removed some constants that are no longer needed 
- Modify MapFile.Reader:
  o added private int seekInternal(WritableComparable) which is basically
      the body of public boolean seek(WritableComparable) but returns the
      integer value of the comparison. This is now called by boolean seek()
  o added public Writable getClosest(WritableComparable, Writable). Unlike
     get which only returns a value on an exact match, getClosest returns the
     value for the key which is closest to the requested key.
