Subject Re: Build failed in Jenkins: Hama-Nightly #645
Date Mon, 20 Aug 2012 18:05:58 GMT
Created an issue for that:
https://issues.apache.org/jira/browse/HAMA-633

2012/8/20 Thomas Jungblut <thomas.jungblut@gmail.com>

> It still fails, omg. I haven't really found the problem yet.
> I suspect some messaging edge case. However, if it is a problem with the
> underlying RPC it would not be triggered in the local mode.
> There must be some wrong behaviour in the "AbstractMessageManager".
> The testcase should be org.apache.hama.examples.ClassSerializePrinting,
> and it does not fail throughout 15 supersteps.
> It seems some really odd edge case.
