There are 2 missing blocks. The following files may be corrupted:
blk_1078468526 /user/spark/sparkstreamingcheckpoint/checkpoint-1517487380000
blk_1078468528 /user/spark/sparkstreamingcheckpoint/checkpoint-1517487400000
Please check the logs or run fsck in order to identify the missing blocks. See the Hadoop FAQ for common causes and potential solutions.
这两个blocks的两个副本都丢失了,所以才导致hdfs发出这个警告。
数据已经无法恢复,只能通过命令删除元数据来消除警告。
