> Here are related logs. dn_10_251_107_213 deleted the block immediately after
> it received it (because of over-replication). However, the information is
> not reported to namenode and name node ask this DN to invalidate the block
> again, causing the error "Unexpected error trying to delete block
> blk_-1201258788540100829. BlockInfo not found in volumeMap.".
