> Key: HAMA-378
> URL: https://issues.apache.org/jira/browse/HAMA-378
> Project: Hama
> Issue Type: Improvement
> Components: bsp
> Reporter: ChiaHung Lin
> Assignee: Edward J. Yoon
> Priority: Minor
>
> When submitting a job, at the server side the GroomServer reports message
> Lost connection to BSP Master [host/ip:port]. Retrying...
> java.lang.NullPointerException
> This seems because the script hama only includes jar files (such as
> hama-0.3.0-examples.jar) located under basedir, the same folder as build.xml.
> Also, a quick check shows that when submitting a job, the ClassLader used is
> sun.misc.Launcher$AppClassLoader, instead of java.net.URLClassLoader. This
> might not be the root cause, but a further investigation may be required.
