Subject [jira] [Created] (HDFS-8121) BlockManager treates normal blocks in a block group as corrput

Li Bo created HDFS-8121:
---------------------------

             Summary: BlockManager treates normal blocks in a block group as corrput
                 Key: HDFS-8121
                 URL: https://issues.apache.org/jira/browse/HDFS-8121
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Li Bo


If a block in a block group is reported by Datanode to Namenode, Namenode will check if it's
corrupt. Currently {{BlockManager}} uses the size of block group to compare with the size
of reported block, which makes the block is treated as corrupt  block by Namenode. I think
Namenode should first calculate the size of the block and then compare it with reported value
