Max August 19th, 2015 Thanks for nice article. If we plan to use Isilon as HDFS storage, we would need only 3 nodes you shown in the picture? all the data nodes would be in Isilon? What traffic would flow thru the pipe between resource manager ( + other nodes you shown ) and Isilon storage? How thick a network pipe would be needed , if we are processing , let’s say 1TB of data an hour?
