Mapreduce jobs running through Edge node

avatar

Hi Folks,

Hope all are doing well.

I've dev setup of 11 node(2x NN, 8x DN, 1x edge node). Basically All nodes are connected by Cluster private(only 11 machine can access to each other) networking. We are using floating IP(public in only organization) on data node as well as on Edge node for access the data from DB.

If we keep floating ip only on Edge node and run MapReduce job from edge node which is importing data from DB to HDFS, i'm getting error that DataNode IP is not able to access to source DB.

Can someone suggest does we require Floating IP on all DataNode machine? Or we can use any other solution?

Will be very thankful to you.

Regards,

Vinay K

@Eric Leme

According to you, we have to open connection from our Datanode to DB server. Edge is not single pain of glass for communication. Need more research..

Well Thanks 🙂
