Giridharan Kesavan commented on HADOOP-5974:
--------------------------------------------

we can file a jira with codehaus with the location of the aspectj jar file and its pom , so
they can help us in uploading the latest version of aspectj to the mvn repository.

BTW I see different aspectj jar file in here .. some of them are at version-1.5.4 and some
are at version 1.6.4
http://www.mvnrepository.com/search.html?query=aspectj

Could you please mention the name of the aspectj jar that you are lookin for?

> It'd be great to have a fault injection mechanism for Hadoop.
> Having such solution in place will allow to increase test coverage of error handling
and recovery mechanisms, reduce reproduction time and increase the reproduction rate of the
problems.
> Ideally, the system has to be orthogonal to the current code and test base. E.g. faults
have to be injected at build time and would have to be configurable, e.g. all faults could
be turned off, or only some of them would be allowed to happen. Also, fault injection has
to be separated from production build.
