什么是端口 9870?
Port 9870 is the default web UI port for the Apache Hadoop HDFS NameNode in Hadoop 3.x. The NameNode web interface provides information about the HDFS cluster, including file system health, DataNode status, and block replication statistics. Earlier Hadoop versions used port 50070 for the same purpose.
