Konstantin Boudnik commented on HADOOP-6073:
--------------------------------------------
I also suggest to change line 555 to
} catch (Exception ioe) {
to make sure that an affected block is properly cleaned.
> Unchecked exception thrown inside of BlockReceiver cause some threads hang

> One is able to inject all sorts of faults into Hadoop's classes using new
> fault injection framework (HADOOP-6003).
> I've been injecting unchecked exception (RuntimeException) into
> BlockReceiver.receivePacket() method before any
> of write() operations (e.g. line 401, 449, 463, 529) and running some of
> the existing HDFS tests. The injection of unchecked exceptions causes
> DataXceiver to die silently and without any traces.
> From a debugger run it seems like some threads are being left alive or not
> notified about the exception.
