问题
command jps shows following details
- 5144 SecondaryNameNode
- 5464 NodeManager
- 5307 ResourceManager
- 5800 Jps
Obviously namenode and datanode are missing
web UI at http://localhost:50070/ doesnt work
but http://localhost:8088/cluster works fine
I am following instructions from https://www.tutorialspoint.com/hadoop/hadoop_enviornment_setup.htm

Your Namenode and Datanode is not running. Look at jps(Namenode and Datanode)has to be listed. Otherwise, you won't see it in http://localhost:50070 assuming you configured single node Cluster.
Please check the Namenode and Datanode logs.
