Konstantin Boudnik commented on HADOOP-6204:
--------------------------------------------
Nicholas has raised the point if we need this modification in place by 0.21
release time.
There are two main reason why I was pushing this into Common right now:
- security tests: aspects framework will allow to test some AccessToken related
functionality without permanent modifications of the production code. I'm not
sure if this functionality will be included into 0.21 so I'd like to see any
input on this
- MR needs aspect framework in place for handling load simulations
(MAPREDUCE-728). If this work doesn't require a permanent aspects framework in
place and can live with a temp. fix then we can postpone this JIRA's commit
past 0.21 release.
Please comment.

> Fault injection framework implementation in HDFS (HDFS-435) turns out to be a
> very useful feature both for error handling testing and for various
> simulations.
> There's certain demand for this framework, thus it need to be pulled up from
> HDFS and brought into Common, so other sub-projects will be able to share it
> if needed.
