Subject [Discuss] Reg : Integration of JCarder or any other power full tool which identifies suspecious deadlock cycles
Date Wed, 24 Dec 2014 10:34:29 GMT

Hi folks,

Recently in YARN project(last 1 year), there 12 deadlock issues or potential deadlock issues
were detected and fixed too. And many more might be there also!!

As going further in production ready releases, point of concern is,  avoiding these type of
issues that may appear in the production deployment which would cause severe impact and loss.
 So if there would be any tool integrated to HadoopQA by default which identifies suspicious
deadlock cycles like JCarder,  then it would be great in identifying  issues in earlier stages
rather than issue reporting after release deploy in cluster.

Any thought or suggestions on this?

Thanks & Regards
Rohith Sharma K S
