HColumnDescriptor's readFields() method is version aware but its write() method is not
--------------------------------------------------------------------------------------

                 Key: HBASE-612
                 URL: https://issues.apache.org/jira/browse/HBASE-612
             Project: Hadoop HBase
          Issue Type: Bug
          Components: io
         Environment: CentOS 5.1 Linux x64_64 / JDK 1.6.0_03-b05
            Reporter: Andrew Purtell
            Priority: Minor
         Attachments: hbase-612-0.2-r652919.patch

HColumnDescriptor's readFields() method is version aware but its write() method is not. 

I found this tracing the cause of a NPE in the Master's IPC server processing a region open
message where the serialized HColumnDescriptor objects were a version earlier than my latest.


Attached is a patch against trunk which cures the problem.
