About HDFS default port 8020

Let's take a look at hadoop the definitive guid tonight. In chapter 3, we will talk about HDFS. I will follow his example to get it done in eclipse.Code, The execution has always reported an error, said not to connect localhost: 8020, I checked the configuration file, it does not have the configuration of this port, but the core-site.xml has a HDFS: localhost: 9000, I think Port 8020 will be enabled by default, but it will not be a problem. Later I saw this blog post for me to try it. The result is right, it may be a legacy configuration problem (the official Quick Start for 0.20.2 is indeed the port 9000Http://hadoop.apache.org/common/docs/r0.20.2/quickstart.html
)
