Konstantin Boudnik commented on HADOOP-5974:
--------------------------------------------
My patch is pretty much ready and requires a couple of libraries to be added to
the Hadoop project. These libraries aren't associated with any of Apache's
projects: they are under Eclipse Software License and are distributed from
their website.
I'm not sure what is the 'rule of thumb' to add the libraries to ivy
configuration for Hadoop? Or shall they be added statically, e.g. into SVN
repository? I assume that the latter is a bad idea generally, which leaves us
with the former option.
Can any of the watchers comment on this, please?
> 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.
