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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
