Aguinaldo Pontes created HAMA-906:
-------------------------------------
Summary: Automatic activation of halted vertices without received
messages
Key: HAMA-906
URL: https://issues.apache.org/jira/browse/HAMA-906
Project: Hama
Issue Type: Bug
Components: graph
Affects Versions: 0.6.4
Reporter: Aguinaldo Pontes
When implementing an algorithm on Apache Hama platform, we noticed that when
the first vertex of the split received a message, all the others became
activated (being previously halted), even if they didn't receive a message.
We think that this happens in the line 254 in GraphJobRunner, in the
doSuperstep method (
https://github.com/apache/hama/blob/trunk/graph/src/main/java/org/apache/hama/graph/GraphJobRunner.java#L254).
We think that in this line it misses the following verification:
if(currentMessage!=null && ... )
Are we right?
