Is it possible to only install Hadoop HDFS

Question

I'm new on Hadoop. I wanted to install mesos with Hadoop HDFS to make a fault-tolerant distributed file system. But everywhere it shows to include many different components.

Can anyone help me?

First of all think of Hadoop as a bundle of services running together, in different nodes in a cluster.

You need to install Hadoop using the zipped version (tar preferably), you can refer to this link https://www.edureka.co/blog/install-hadoop-single-node-hadoop-cluster

 I think HDFS and mapreduce come from different rpm packages, but it does harm to install both rpm packages. Again just run NameNode and DataNodes if you only need HDFS.
