Document Store (DOT) on HBase (was RE: Project Panthera status)
Hi Ted,

Sorry for the late reply - most of us are out due to Chinese New Year holidays.

The document store (DOT) code is currently added to pom.xml as a profile, and therefore you will need to build it using "mvn compile/package -Pdot" (see https://github.com/intel-hadoop/hbase-0.94-panthera/blob/master/BUILD.txt). We have also updated readme accordingly.

For DOT code base, we have been following the suggestions from the community (e.g., HBASE-6800<https://issues.apache.org/jira/browse/HBASE-6800> and HBASE-6805<https://issues.apache.org/jira/browse/HBASE-6805>), and factoring the code as a separate co-processor application to HBase (rather than replicating the HBase code). We have made the necessary changes to HBase infrastructure (see HBASE-7387<https://issues.apache.org/jira/browse/HBASE-7387>), and are in the process of refactoring the code (using a custom StoreScanner as suggested in HBASE-6805<https://issues.apache.org/jira/browse/HBASE-6805>.)

Thanks,
-Jason

I checked out git://github.com/intel-hadoop/hbase-0.94-panthera.git<http://github.com/intel-hadoop/hbase-0.94-panthera.git> today and I got the following compilation error:

The last checkin was done on Sep 18, 2012

Is this project actively maintained ?

Thanks
