Subject Re: Sqoop vs spark jdbc
Date Wed, 24 Aug 2016 22:07:20 GMT
Personally I prefer Spark JDBC.

Both Sqoop and Spark rely on the same drivers.

I think Spark is faster and if you have many nodes you can partition your
incoming data and take advantage of Spark DAG + in memory offering.

By default Sqoop will use Map-reduce which is pretty slow.

Remember for Spark you will need to have sufficient memory
