[jira] [Created] (HDFS-15795) Returned wrong checksum when reconstruction was failed by exception

Yushi Hayasaka created HDFS-15795:
-------------------------------------

             Summary: Returned wrong checksum when reconstruction was failed by exception
                 Key: HDFS-15795
                 URL: https://issues.apache.org/jira/browse/HDFS-15795
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode, ec, erasure-coding
            Reporter: Yushi Hayasaka


If the reconstruction task is failed on StripedBlockChecksumReconstructor by exception, the checksum becomes wrong one because it is calculated with blocks without a failure one.
It is caused by catching exception with not appropriate way, so we need to fix it.
