Bumped mailbox API version to 0.3

This is another status update on the James HBase mailbox implementation. I am now following apache-james-mailbox-0.3 release.
At first I tried following trunk, but got overwhelmed by the speed of changes in the code. That led to a discussion on the mailing list that concluded with the me following release 0.2.

Now that the mailbox API is stable in 0.3 I am going to follow this branch. Some of the improvements worth mentioning are:
  • simpler API for managing messages
  • lucene index for searching
  • support for quotas

The full list is available on jira.

The other thing I was working on, the link to HBase, is not done yet. I am getting an exception in HBaseStoreTest.java:

java.lang.NoClassDefFoundError: org/apache/hadoop/security/UnixUserGroupInformation
at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniDFSCluster(HBaseTestingUtility.java:223)

I think I may have a HBase library that is incompatible with the Hadoop version. I will check this soon and post what I find.

Any suggestions are appreciated.
