Lost connection to BSP Master [host/ip:port]. Retrying...
-----------------------------------------------------------
Key: HAMA-378
URL: https://issues.apache.org/jira/browse/HAMA-378
Project: Hama
Issue Type: Improvement
Components: bsp
Reporter: ChiaHung Lin
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.
