I am trying to setup druid (Load batch data using hadoop

Hi,

I am following http://druid.io/docs/latest/tutorials/tutorial-batch-hadoop.html, I am not sure how to reach this cd /usr/local/hadoop/bin

I did brew install hadoop and have this folder structure** cd /usr/local/Cellar/hadoop/3.1.1/bin/**

Tried to do the following, but getting an error mkdir: `/druid’: Input/output error

./hadoop fs -mkdir /druid
