Subject [jira] [Updated] (HAMA-437) PiEstimator is not working in Local Mode
Date Fri, 16 Sep 2011 19:06:12 GMT

     [ https://issues.apache.org/jira/browse/HAMA-437?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Thomas Jungblut updated HAMA-437:

    Attachment: HAMA-437.patch

I have fixed PiEstimator now, it works in both modes.

Additionally I have added some outputs when starting a cluster in local mode, because I had
some mailing list fun the last days.

If the apps determine that there is "local" in "bsp.master.adress" then the application exits
and prints that it doesn't need to be started.
This will now prevent the questions: "my error log shows, local is no valid hostname". Although
I think this is a pretty clear exception >_>.

Anyways, you can now submit local jobs via the shell ./hama jar <jar.jar> test for example.

And I added testcases for the local mode and fixed a bit with the name handling in our cluster

There were a hell lot of other problems, for example a local running BSP that could not work
on DFS because the filename wasn't qualified with hdfs://.

And I added a better exception if a host+port string, that is given in the send method will
not be splittable by ":".

I wish the person how want to test this the best of luck :D

> While playing arround in HAMA-436, I observed that PiEstimator is not working in local
mode because of the peer name manipulation.
> Shortest Paths and Pagerank are working because they use the hostname directly without
constructing it with a default port.
> Additionally we should add a TestCase for the LocalBSPRunner that launches the PiEstimator.
