             Summary: Distcp should not copy replication factor if source file 
is erasure coded
                 Key: HDFS-10971
                 URL: https://issues.apache.org/jira/browse/HDFS-10971
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: distcp
    Affects Versions: 3.0.0-alpha1
            Reporter: Wei-Chiu Chuang
            Assignee: Wei-Chiu Chuang


The current erasure coding implementation uses replication refactor field to 
store erasure coding policy.

Distcp copies the source file's replication refactor to the destination if -pr 
is specified. However, if the source file is EC, the replication factor (which 
is EC policy) should not be replicated to the destination file.

In fact, I will attach a test case that shows trying to replicate the 
replication factor of an EC file results in an IOException: "Requested 
replication factor of 0 is less than the required minimum of 1 for 
/tmp/dst/dest2"
