Connecting JConsole to ResourceManager
Hi All,
I am trying to connect to a running ResourceManager process on Windows. I
ran jconsole and it shows the ResourceManager process. When I try
connecting, it immediately fails saying that it cannot connect.
I verified that the cluster is running fine by running the wordcount
example.
Please advise.
Regards,
Atri

Thanks Rakesh.
I have all of that setup. I am intermittently able to connect but then not
again.
I had a quick question. Can I use localhost:8080/jmx to view the counters
registered with metrics2 framework? I added some RPC counters and
registered my new class with DefaultMetricsSystem.
Regards,
Atri

Hi Atri,
Do you meant, something like, jconsole [processID].
afaik, the local jmx uses the local filesystem. I hope your processes are
running under same user to ensure there is no permission issues. Also,
could you please check %TEMP% and %TMP% environment variables and make sure
YOUR_USER_NAME in this is exactly same(I meant, case sensitive). I had
observed some problematic cases like directory created with lowercase
letters and username with uppercase letters.
Thanks,
Rakesh

Thanks Rohith.
I am running JConsole locally on the same machine as I have my single node
cluster.Do I still need to enable remote access?

Hi
Have you enabled JMX remote connections parameters for RM start up? If you are trying to remote connection, these parameter supposed to passed in hadoop opts
You need to enable remote by configuring these parameter in RM jam start up.
-Dcom.sun.management.jmxremote.port=9999 \
-Dcom.sun.management.jmxremote.authenticate=false \
-Dcom.sun.management.jmxremote.ssl=false
