      Description

      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.
