Can't launch Flink on Hadoop cluster: Call From localhost.localdomain/127.0.0.1
to localhost:36063 failed
Hi,
I'm trying to launch Flink as a long-running Yarn app (on Hadoop 2.8.3),
which should be simple as running `./yarn-session.sh`, but something is not
working here.
When I run said command, I get the following error:
Error while deploying YARN cluster: Couldn't deploy Yarn session cluster
[...]
Diagnostics from YARN: Application application_1517332236216_0002 failed 1
times (global limit =2; local limit is =1) due to Error launching
appattempt_1517332236216_0002_000001. Got exception:
java.net.ConnectException: Call From localhost.localdomain/127.0.0.1 to
localhost:36063 failed on connection exception: java.net.ConnectException:
Connection refused; For more details see:
http://wiki.apache.org/hadoop/ConnectionRefused
So here is the weird part: I'm just running namenode, datanode on that
server. I want it to be the master machine so I'm not running
resourcemanager on it. There is another machine running resourcemanager and
I did the whole shebang to make it visible to the master node.
So I'm not sure why it's trying to connect to localhost or even who should
be listening on port 36063. At first I thought it was a problem with the
Flink package (dunno, maybe they hardcoded that port in their package or
something) but it really seems to be a problem with my install (and I have
absolutely no more ideas on what to look for).
Anything else I should be looking for?
