To be clear, you have two clusters, and you're interested in moving a table's data but not necessarily it's operational load? There is probably a migration path involving table snapshots, though I've not tried it myself. It would look something like the following:
- major compact the table to ensure it's data files are all HFileV2 - create a snapshot of the table - export the snapshot to a path on HDFS - copy the export to the new cluster, probably with distcp or webhdfs - import the snapshot into HBase on the new cluster I have limited experience with the snapshot features, so I may be missing some steps.
