In which directory Hadoop should be installed

0 votes

I am setting up Hadoop (3 node cluster) in my college lab. I am using Ubuntu 16.04. My major problem is that the /usr/local of all the machines are mounted from same disk. So all of them have the same shared disk.
Thus I cannot start separate data nodes on slave machine as they will always be similar.

Can I install Hadoop in other directory (not in /usr/local).

Can I install Hadoop in different directory? Will it be creating a problem for me later on?

You can install Hadoop anywhere. You just have to specify the path of the directories in .bashrc file present in user home directory. HADOOP_HOME should point to path where the Hadoop directory is extracted.

Update the .bashrc as follows:

export HADOOP_HOME=/path/to/Hadoop_directory

export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
