Re: [smila-dev] Zookeeper fatal error and SMILA shutdown

Hi Peter,

 

never saw something like that with zookeeper before. (NoClassDefFoundError ???)

 

Are you doing something special in that branch? Is it possible that the main error happened before and this was a subsequent error?

 

Best Regards,

Andreas

Betreff: [smila-dev] Zookeeper fatal error and SMILA shutdown

 

Hi folks,

 

lately I was wondering why my SMILA instance doesn’t answer anymore. When I took a look in log file I found this exceptions followed by a graceful shutdown of the framework:

Does anyone has an idea what was happening and how I can avoid such behavior?

I’m using the branch “2012-01-27_r2218_v1.1-prep” in SMILA SVN.

 

Thanks you.

 

Best regards

 

Peter
