How does one schedule mappers to read MongoDB or HBase in a data-locality-aware fashion? -john

Through this adapter you can pull the data, process it and push it back to your MongoDB backed datastore by writing MR jobs. It is also 100% possible to query Hbase or JSON files, or anything else for that matter, stored in HDFS.

Or is it possible to query hbase or json files stored in hdfs in a similar way as we can query the json documents in mongodb. Suggestions please. Thank you. Regards, Panshul.
