An issue in which HDFs Web UI extranet is inaccessible in CDH

In fact, the problem is very simple, because in the CDH hdfs-site.xml configuration file in the Web UI configuration is the domain name, and the domain name in the hosts have been parsed into the intranet IP.

You use NETSTAT-APN | grep 50700 Look at the listening situation.

You will find that your network IP is listening, not the extranet IP, so HDFs Web UI is inaccessible.

WORKAROUND: If you are using Apache Hadoop, then you need to manually modify the Hdfs-site.xml dfs.namenode.http-address and modify it to 0.0.0.0:50070. If you are using Clouderamanager, then go to hdfs-> configuration, search Namenode default group, and then put the Namenode default group on the circle.

Note When the adjustment is complete, you need to restart HDFs
