----------------------------------

             Summary: Erasure Code(6:3) can not work, using get fs shell when 2 datanode down
                 Key: HDFS-10697
                 URL: https://issues.apache.org/jira/browse/HDFS-10697
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: erasure-coding
    Affects Versions: 3.0.0-alpha2
         Environment: 9 datanodes 2 HA name node and Yarn
            Reporter: Alberic Liu


I can put file into EC folder(6:3), and get the file successfully.
But when I shutdown one datanode, I still can get the file, using hdfs dfs -get.
But when I shutdown two datanodes, when i use hdfs dfs -get, I get following error:
get: 4 missing blocks, the stripe is: Offset=786432, length=65536, fetchedChunksNum=5, missingChunksNum=4;
locatedBlocks is: LocatedBlocks{
