> 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.
