visor freezes

asked by od

version 1.0.0-incubating: I have a 5 machine cluster on EC2 that runs 1.0.0-incubating using the example-ignite.xml configuration. When I run the visor program and "open" the same config, the visor program just hangs. This worked just fine (with example-cache.xml, for example, in RC1).

I should add that it freezes at this point: +------------------------------------------------------------------------------+ | Using configuration | /home/deploy/ignite/examples/config/example-ignite.xml | +------------------------------------------------------------------------------+

Can you attach here a thread dump of the hung process?

We are investigating this issue. Could you provide more information about your cluster and how you start nodes? Do you have linux cluster? Do you start Visor cmd on EC2 or on local machine?

Alexey, the cluster is 5 EC2 instances running Linux (I believe Ubuntu). I am not a Java person - how do I get a thread dump of the hung process? Or do you just want me to attach with gdb?

In the same discussion, I have noticed that since 1.0.0-incubating, adding machines/jvms to a cluster gets slower and slower with each new machine/jvm.

Another question is: what ports tcp and udp need to be open/allowed (on Amazon or via iptables) on the machines in an Ignite cluster for all the "communication lines" to be open?

OD, in couple of days new version of Ignite will be released. Could you try Visor with new version once it will be available?
