Subject [jira] [Commented] (HDFS-12919) RBF: Support erasure coding methods in RouterRpcServer
Date Fri, 12 Jan 2018 08:55:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16323719#comment-16323719
] 

Yiqun Lin commented on HDFS-12919:
----------------------------------

Overall looks good. Two minor comments related to method {{TestRouterRpc#getFileDFSClient}}.

* Would you use LOG instance to print track info as well?
* The parameter passed in {{getFileDFSClient}} seems not correct.
{code}
    assertTrue(verifyFileExists(routerFS, filePath3));
+    DFSClient file3Protocol = getFileDFSClient(filePath1);
{code}
I think here should be filePath3, the same problem to filePath2.
After this, It would be better to let  [~eddyxu] have a look. He will be more familiar than
me with HDFS EC.
