Subject [jira] Created: (HAMA-39) Defining exception policies
Date Thu, 21 Aug 2008 13:34:44 GMT
Defining exception policies 
----------------------------

                 Key: HAMA-39
                 URL: https://issues.apache.org/jira/browse/HAMA-39
             Project: Hama
          Issue Type: Improvement
            Reporter: Edward J. Yoon
             Fix For: 0.1.0


Each operations should have a throws clause.

----
In class AbstractMatrix, the exception will be catch to call only LOG.error.
I would like to discuss a bit more on this issue that how the system
should do when an exception is thrown.
But I don't think only logging an error is not enough.

1. re-throw the exception. This needs changes of the interface,
probably we could have the new ComputationException class, or
something.
2. throw a runtime expection, and of course JVM will die here.

Regards,

Chanwit
