hi,
We are getting the following error while connecting to HDFS through Big Data File Stage
Unable to connect to host hdfs server though port 9000.
Can anyone who worked on bdfs stage let us know what is causing this error.
The biginsights server is pinging fine from DS Engine server.
Thanks.

Can you check that the Hadoop server is listening (successfully) on port number 9000? This is the next step on from a ping test, which only shows network connectivity. Use netstat and, perhaps, telnet commands to test the port.

The Hadoop server is listening fine. Below is the exact error which we are facing :
Unable to connect to hdfs host on port 9000: Socket operation on non-socket.

We have used netstat and telnet commands to test the port. The Biginsights (hdfs) machine is listening fine too. Below is the exact error we are getting.
Unable to connect to hdfs host on port 9000: Socket operation on non-socket.
Thank you.

Did you find a solution for this connection issue?
We are are getting the same error on a new DS 9.1.2 installation while old DS 8.7 connecting to the same HDFS can connects fine.
