Hi Team,
I did not find much info as how to connect MongoDB to Hadoop using Sqoop connectivity. Does sqoop work with MongoDB Hadoop .
If sqoop works with mongoDB Hadoop connector how should the query look like to pull incremental data?
Ashvanth Rameshkumar.
These are the minimum versions tested with the Hadoop connector. Earlier versions may work, but haven't been tested.
You must have at least version 3.0.0 of the MongoDB Java Driver installed in order to use the Hadoop connector.
Have fun,
Shiv

I am pulling Bson data from MongoDB to Hadoop and when the data is at destination what will be format/type of data ??
Hi Ashvanth,
The MongoDB Connector for Hadoop makes it easy to use MongoDB databases, or MongoDB backup files in bson
format, as the input source or output destination for Hadoop Map/Reduce jobs.
If you are referring to reading MongoDB back up files in bson
format. i.e. output of mongodump , see Using BSON Files for usage and examples. If you are reading from MongoDB database as input/output source, see Configuration Reference for more information.
In regards to the input format, it depends on what you are trying to do. There are a number of input formats: com.mongodb.hadoop. Check out the MongoDB Hadoop Connector Job Examples for examples map/reduce jobs.
