What port does Isilon use for WebHDFS?
Hi,
Does anybody know which port# Isilon uses/listens for WebHDFS access?
Client sends a request using port# 50070 but Isilon replies back to ACK+RST. So, the connection fails.
Since I found below info, I tried to use port# 8082 but the result did not change...

I also checked the listening ports (netstat -nat | grep LISTEN) and found obviously the Isilon did not listen port# 50070 nor 8082.
What port does Isilon use for WebHDFS?
FYI: Of course, WebHDFS Enabled=Yes.

Check which port is actually configured with isi_gconfig,
and then have another look at netstat.
(On our cluster running 7.2.0.4 it is in fact 8082.)
# isi_gconfig -t web-config webhdfs_port
webhdfs_port (int) = 8082
# netstat -nal | grep 8082
tcp46 0 0 *.8082 *.* LISTEN
And of course:
# isi services isi_hdfs_d
Service 'isi_hdfs_d' is enabled.
# isi services apache2
Service 'apache2' is enabled.

The hdfs url is fs.defaultFS is port 8020
BUT dfs.namenode.http-address is 8082, not 8020
(i believe the Ambari default is 50070, we are using a different port but not 8020)

Thank you for the info!
We could finally access to Isilon through TCP 8082 by WebHDFS
