Has anyone developed tools to migrate data from an existing HBase implementation to Accumulo? My team has done it "manually" in the past but it seems like it would be reasonable to write a process that handled the steps in a more automated fashion.
Here are a few sample designs I've kicked around: HBase -> mapreduce -> mappers bulk write to accumulo -> Accumulo or HBase -> mapreduce -> tfiles via AccumuloFileOutputFormat -> Accumulo bulk load -> Accumulo or HBase -> bulk export -> map-only mapreduce to translate hfiles into tfiles (how hard would this be??) -> Accumulo bulk load -> Accumulo I guess this could be extended to go the other way around (and also include Cassandra perhaps). Maybe we'll start working on this soon. I just wanted to kick the idea out there to see if it's been done before or if anyone has some gut reactions to the process. -Don -- This communication is the property of ClearEdge IT Solutions, LLC and may contain confidential and/or privileged information.
