Tsz Wo Nicholas Sze created HDFS-8289:
-----------------------------------------

             Summary: DFSStripedOutputStream uses an additional rpc all to getErasureCodingInfo
                 Key: HDFS-8289
                 URL: https://issues.apache.org/jira/browse/HDFS-8289
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


{code}
    // ECInfo is restored from NN just before writing striped files.
    ecInfo = dfsClient.getErasureCodingInfo(src);
{code}
The rpc call above can be avoided by adding ECSchema to HdfsFileStatus.
