Subject [jira] Commented: (HADOOP-1325) HBase code update 0.0.0-2
Date Fri, 04 May 2007 03:22:15 GMT

Jim Kellerman commented on HADOOP-1325:
---------------------------------------

This is the first release of HBase that is really ready for evaluation.

The client, master, and region server all basically work.

Do it cover edge cases or failover? NO.

However, for preliminary evaluation, this release is at least functional from the client ->
master -> regionserver.

If you use/evaluate HBase and find problems, please enter a Jira issue with the component
contrib/hbase.

Thanks, and enjoy!
