> Corrupted blocks by definition are blocks cannot be read. As a consequence,
> they cannot be replicated. In UnderReplicatedBlocks, there is a queue for
> QUEUE_WITH_CORRUPT_BLOCKS and chooseUnderReplicatedBlocks may choose blocks
> from it. It seems that scheduling corrupted block for replication is wasting
> resource and potentially slow down replication for the higher priority blocks.
