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

Yes. You can use MongoDB-Hadoop adapter to achieve that. 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.

Warm Regards,

Is it possible or how is it possible to query mongodb directly from hadoop.

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.
