[jira] [Commented] (HADOOP-15883) Fix WebHdfsFileSystemContract
test
[ https://issues.apache.org/jira/browse/HADOOP-15883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16666407#comment-16666407 ]
He Xiaoqiao commented on HADOOP-15883:
--------------------------------------
[~jojochuang],[~ayushtkn] As HADOOP-15864 mentioned, after patch, DataNode will NOT meet IllegalArgumentException when create DFSClient instance, however, when DataNode creates wrapped outputstream, it will meet auth exception since no token exist, so Client will meet HTTP status code 403.
In one word, this patch changes http semantic when no parameter about #namenoderpcaddress.
On the base of the above, I support also change http status code to 403 when checking at TestWebHdfsFileSystemContract#testResponseCode. FYI.
