Konstantin Boudnik commented on HADOOP-5974:
--------------------------------------------
Thanks for the suggestion, Nicholas. I like your way (the prefixing with
fault.probability) better and I'm putting it into the patch right away.
As for suffix of the name it'd be completely up to the aspects developers to
name it. However, I agree that datanode.BlockReceiver would more mnemonically
appealing.
> Add orthogonal fault injection mechanism/framework

> 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.
