Hi ,
We have setup a Spark Cluster (3 node) on Amazon EMR. We aren't able to use port 9026 and 9101 on the existing Spark EMR Cluster which are part of the Web UIs offered with Amazon EMR. I was able to use other ports like Zeppelin port, 8890, HUE etc We checked that the security settings currently are open to everyone, and it is not an issue with security. URLs Hadoop ResourceManager http://master-node-IP:9026/ Hadoop HDFS NameNode http://master-node-IP:9101/ Errors Observed on Fiddler: Port 9026: [Fiddler] The connection to 'masternodeIP' failed. Error: TimedOut (0x274c). System.Net.Sockets.SocketException A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond <<MasternodeIP>>:9026 Port 9101: [Fiddler] The connection to <<MasternodeIP>>: failed. Error: TimedOut (0x274c). System.Net.Sockets.SocketException A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond <<MasternodeIP>>:9101 Does anyone have any experiences or pointers?
