Very cool stuff! And the guide is very helpful. I have some questions from the
user gide.
{quote}
pointcut callReceivePacket() :
call (* OutputStream.write(..))
withincode (* BlockReceiver.receivePacket(..))
// to further limit the application of this aspect a very narrow
'target' can be used as follows
// target(DataOutputStream)
!within(BlockReceiverAspects +);

Can you pl explain the above line in detail, what it means, etc. Things like
pointcut, withincode, are these aspectJ constructs? what is the intention
of the above line? Thanks.

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.
