Hello there,
I've seen that you resolved the HAMA-789. So, is it going to be
available in a new version? How do we define the specific port we want?

Another error came up! Now it starts zookeepers but loses the connection.

So I think that the problem again is the port restriction. The 49564 port is
randomly selected again. I tried seting it at the zookeeper quorum servers
like host:port1:port2 but still it chooses randomly. Is there any way to
"standarize" it like with groomserver?

Thanks a lot Edward! I will try it and let you know if something comes up!
Have a nice day!

Again,
You can specify the report server port by setting
"bsp.groom.report.address" property like below:
<property>
<name>bsp.groom.report.address</name>
<value>127.0.0.1:5001</value>
</property>
Default value was 127.0.0.1:0. (random port).

Oh, .. thanks.
The GroomServer.taskReportServer seems uses random port. I'll make it
configurable.

Hey,
So what the IPC Server stands for and it gets random ports? I ve seen
39865
and 52765. What is the deal with it?

Hi,
a Hama cluster uses ports "bsp.master.port" 40000 and
"bsp.groom.rpc.port" 50000 to communicate among the cluster nodes.
And the default peer port is 61000. If you set 3 for the maximum
number of tasks per node, each task uses ports from 61000 to 61003 to
transfer messages between bsp tasks.

Hello there,
I am trying to setup Hama in a cluster with really strict port
permissions
and I get across the error at every GroomServer:
"There is a problem in establishing link with BSPMaster."
- Do you know what is the range of ports that every GroomServers IPC
Server
gets when started?
- Is there a way to limit this range to new user values?
Thank you.
