[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.
