Hey Bradford, Disclaimer: I don't know exactly what's in CDH3B3, so this is a bit uninformed...
Are you using an ASF HBase 0.20.6? If so, I don't think that'll work with CDH3B3 Hadoop, since it includes the secure Hadoop changes. Even without enabling the security features (hadoop.security.authentication=simple -- the default), there are still backward incompatible changes to core Hadoop classes like org.apache.hadoop.security.UserGroupInformation that will bite you. You can't even compile stock HBase against secure Hadoop. So I think running CDH3B3 Hadoop means you need to run CDH3B3 HBase. Cloudera folks, please correct me if I'm wrong. I hope to work up some patches to allow HBase trunk to work on both secure Hadoop plus just 0.20-append, but it will take a little work due to the backward-incompatible changes. --gh On Tue, Oct 26, 2010 at 12:13 AM, Tao Xie <[email protected]> wrote: > I once have same problem.
