    While the bulk load utility exists, there isn't any sort of bulk unload utility to pull data out of a MapRDB table and into another format.

     

    Hbase does have a tool that dumps hfiles in to  sequence files...  it would be nice to dump HFiles in to ORC / Parquet or even csv files...

     

    This assumes that you have a known schema for the table and couldn't be used for non-structured tables unless you're dumping this as a strict key/value pair and the value is a blob row space.
