Subject [jira] [Created] (HDFS-12579) JournalNodeSyncer should use fromUrl field of EditLogManifestResponse to construct servlet Url

Hanisha Koneru created HDFS-12579:
-------------------------------------

             Summary: JournalNodeSyncer should use fromUrl field of EditLogManifestResponse
to construct servlet Url
                 Key: HDFS-12579
                 URL: https://issues.apache.org/jira/browse/HDFS-12579
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Hanisha Koneru
            Assignee: Hanisha Koneru


Currently in JournalNodeSyncer, we construct the remote JN http server url using the JN host
address and the http port that we get from the {{GetEditLogManifestResponseProto}}.
{code}
          if (remoteJNproxy.httpServerUrl == null) {
            remoteJNproxy.httpServerUrl = getHttpServerURI("http",
                remoteJNproxy.jnAddr.getHostName(), response.getHttpPort());
          }
{code}

The correct way would be to get the http server url of the remote JN from the {{fromUrl}}
field of the {{GetEditLogManifestResponseProto}}. This would take care of the http policy
set on the remote JN as well.
