HuangTao created HDFS-14770:
-------------------------------

             Summary: Erasure Coding: reconstructed internal block is error
                 Key: HDFS-14770
                 URL: https://issues.apache.org/jira/browse/HDFS-14770
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode, erasure-coding
            Reporter: HuangTao


We found some missing EC internal blocks were reconstructed incorrectly.

The incorrect block(md5sum)

{code:java}
73ceb92c4223ce00ff88802fdafd19a3  /data5/dfs/current/BP-XXXXXX/current/finalized/subdir6/subdir7/blk_-9223372036570159327
{code}

It should be

{code:java}
137e1c8483126291c2e84fc0115cfcc6  /data3/dfs/current/BP-XXXXXX/current/finalized/subdir7/subdir6/blk_-9223372036401277247
{code}
