What is Hadoop Administration?
Hdfs administration and MapReduce administration, both concepts come under Hadoop administration.
- Hdfs administration: It includes monitoring the HDFS file structure, location and updated files.
- MapReduce administration: it includes monitoring the list of applications, configuration of nodes, application status.

We can see the below screenshot using the url to the browser <http://localhost:50070> after passing the command “start-all.sh” on “/$HADOOP_HOME/sbin”.
The most two important things in this concept are
- Suitable datanode configuration in application
- For each application, number of datanodes and resources
