J.Andreina commented on HDFS-9495:
----------------------------------
Currently in DatanodeHttpServer, we are passing the port as 0 (which means
random port ) for endpoint that HTTP server would listen to.
{code}
HttpServer2.Builder builder = new HttpServer2.Builder()
.setName("datanode")
.setConf(confForInfoServer)
.setACL(new AccessControlList(conf.get(DFS_ADMIN, " ")))
.hostName(getHostnameForSpnegoPrincipal(confForInfoServer))
.addEndpoint(URI.create("http://localhost:0";))
.setFindPort(true);
{code}
We can make it configurable and provide a default port instead of taking up a
random.
Please provide your feedback.
