Performance of a Sqoop import

[#1]

What decides the speed of Sqoop operation? Sqoop runs on the Edge node, isn' it? Then whether the number of data nodes in a cluster has any impact on the performance of a Sqoop import?

There are a couple of factors, it has best been summarized in this HCC document SQOOP Performance tuning

Hope that helps

There are some factors which are affecting performance of sqoop import.

1. Network Bandwidth between source server (Oracle, MySQL, PostgreSQL) and destination server (Datanodes).

2. Source server's connection policy for clients.

3. CPU, RAM, DISK Performance listing of servers.
