关于hdfs集群中Please check the logs or run fsck in order to identify the missing blocks. See the Hadoop F

Please check the logs or run fsck in order to identify the missing blocks. See the Hadoop FAQ for common causes and potential solutions.

hadoop  fsck 

hadoop  fsck -delete

原因分析:
删除了几个hdfs上的数据,然后就出现这个问题,异常信息
​ 在hdfs中数据是按块方式(blk_1073748128没理解错误就是一个块)存储的,删除了blk_1073748128后,元数据还在,但是数据块不在了,才报的这个错,但是这部分数据其实不需要了,所以可以直接将异常的文件块的元数据信息也删除。
