Although I can find the Agent.pid file in pidDir directory, the
Collector.pid file is absent. And because of this the system is not
able to retrieve the PID of collector process.As a result kill is also
not working for collector.Any comments???

Regards,
    Mohammad Tariq

Collector and agent share the same code for pid file locking.  You may want
to check $CHUKWA_HOME/conf/chukwa-env.sh on the collector machine
and make sure

export CHUKWA_PID_DIR
is setup correctly.

Eric

Chukwa is working fine with Hadoop-0.20.2..Earlier I was using
0.20.203.0 and it had the same configuration just as 0.20.2..but it
was not working earlier.I am able to start both agent and collector
properly

Hi Ahmed,

   When I am pointing my web browser to " http://localhost:8080/hicc "
the only thing which I can see on the browser is " Chukwa servlet
running "..and in the logs it is showing that address 8080 is already
in use, although I have changed the tomcat port to 8090.I am using
0.4.0..What might be the cause???

    Mohammad Tariq

Hi Tariq,

Chukwa hicc and collector are designed to run on different servers.
Hence, it is probably best to use alternative port for Chukwa
collector.  The port number for Chukwa collector can be adjusted in
chukwa-collector-conf.xml with chukwaCollector.http.port setting.
"collectors" file should contain http://localhost:8090/ for agent to
push events to collector.

regards,
Eric

I have changed the collector port and now when I point my web browse
to " http://localhost:8080/hicc/ " it shows me -

"HTTP Status 503 - This application is not currently available"

The HiccWebServer is running/

It looks like there is another instance of HICC running.

I can see only one HICC instance running on my machine. Do I need
jetty and tomcat running simultaneously on my machine???

No, you don't...

Can you check what's listening on the port in question? I think you can use
the netstat command for this or something.

Ahmed Fathalla

Chukwa was designed to run from either jetty or tomcat, but only one
web servlet container is required for deployment.  I would recommend
to use bin/chukwa hicc to start HICC.  The tomcat deployment approach
is deprecated in Chukwa 0.1.2.

Eric
