Re: Samza yarn job - cannot bind to local host

Hey Shekar, Yes, https://issues.apache.org/jira/browse/SAMZA-825 seems to fit the bill. It hasn't been high priority because most users run samza in YARN or some other multi-tenant environment s.t. the ephemeral ports are ideal. However with the upcoming standalone support, this makes more

Re: Samza yarn job - cannot bind to local host

Just following on the same thread, is there a feature/bug to force the jmxrmi port? This would be helpful to get the container metrics. - Shekar On Sat, Aug 6, 2016 at 6:14 PM, Shekar Tippur wrote: > Thanks a lot guys. It was a system problem. /etc/hosts file had wrong >

Thanks a lot guys. It was a system problem. /etc/hosts file had wrong permissions. localhost was being resolved to a weird ip for certain users via DNS. - Shekar On Fri, Aug 5, 2016 at 11:27 AM, Jacob Maes wrote: > Hey Shekar, > > There's currently no way to force the port

Re: Samza yarn job - cannot bind to local host

Hey Shekar, There's currently no way to force the port or disable the JMXServer. We've seen port conflicts (fixed in 10.1) and connection issues due to VPN but no connection issue for other reasons. While googling that exception, I found a couple cases without clear resolutions, but they were

Re: Samza yarn job - cannot bind to local host

Hey Shekar, Are your YARN hosts connected to a VPN by chance? The only time I've seen problems with the localhost was when I ran unit tests on my Mac while connected to VPN. Apparently, its related to a bug in Java http://bugs.java.com/view_bug.do?bug_id=7180557 -Jake On Thu, Aug 4, 2016 at

Re: Samza yarn job - cannot bind to local host

Sorry .. got trigger happy. Couple of observations: 1. rmi port seem to be random ones Even with task.opts and setting the port to 1099 2. Do I need to start rmiregistry manually? 3. I dont have any firewall settings. On Thu, Aug 4, 2016 at 12:14 PM, Shekar Tippur wrote: > Yi

Re: Samza yarn job - cannot bind to local host

Yi Thanks for responding.. I have tried diff options for task.opts and without it as well. I have tried this task.opts=-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

Re: Samza yarn job - cannot bind to local host

Hi, Shekar, Did you check your firewall configuration? Could you also paste your configuration, especially task.opts? -Yi On Wed, Aug 3, 2016 at 5:56 PM, Shekar Tippur wrote: > I am trying to submit a Samza job to yarn and I get a error: > > Exception in thread "main"
