             Summary: HttpFS: WebHdfsFileSystem cannot renew an expired delegation token from HttpFS response
                 Key: HDFS-15474
                 URL: https://issues.apache.org/jira/browse/HDFS-15474
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Takanobu Asanuma
            Assignee: Takanobu Asanuma


When clients use WebHdfsFileSystem for HttpFS, they cannot renew expired delegation tokens with the following error.
{noformat}
org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.security.token.SecretManager$InvalidToken: token (owner=..., renewer=..., realUser=..., issueDate=..., maxDate=..., sequenceNumber=..., masterKeyId=...) is expired
        at org.apache.hadoop.hdfs.web.JsonUtilClient.toRemoteException(JsonUtilClient.java:89)
        at org.apache.hadoop.hdfs.web.WebHdfsFileSystem.validateResponse(WebHdfsFileSystem.java:509)
        ...
{noformat}
When using WebHdfsFileSystem for NameNode, it succeeds. This is because the response of HttpFS is different from its of NameNode. We should fix the response of HttpFS.
