Hadoop startup times wrong: Incorrect configuration:namenode address dfs.namenode.servicerpc-address or ...

Hadoop was good before it started this morning with a sudden error:

incorrect Configuration:namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not Configured.

In a disorderly search on the internet, a variety of ways to try, have not solved the problem. At this point, it suddenly occurred to me that the problem might have been caused by some of the changes that were made yesterday to start correctly between today's startup errors, and most likely because the environment variables were modified yesterday when Mahout was installed. So I deleted the Hadoop-related environment variables that were added because of mahout in. Profile, and the deleted configuration is as follows:

Export hadoop_conf_dir= $HADOOP _home/etc/hadoop

Then, Hadoop can start correctly.

(Always after a stumble, to clear the mind and make things clear.) The realm is not enough, come on. ）
