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.
