> {{BlockManager.invalidateCorruptReplicas()}} iterates over DatanodeDescriptor-s while
removing corrupt replicas from the descriptors. This causes {{ConcurrentModificationException}}
if there is more than one replicas of the block. I ran into this exception debugging different
scenarios in append, but it should be fixed in the trunk too.
