How to map hive warehouse path in hive-site.xml? - hadoop

Question

I'm new to ubuntu, and I'm trying to install hive 3.0.0 on my system.
I'm following a tutorial on internet and I came across this command.
hdfs dfs -mkdir -p /user/hive/warehouse
hdfs dfs -mkdir /tmp
This command are used to store metadata. But I can't find those in filesystem.
So my question is that, what is the meaning of this commands?
And how to map that metadata on hive-site.xml?
Following is the hive-site.xml from my tutorial.

Answer 1

This command are used to store metadata
Not quite. That's the Hive Warehouse directory on HDFS. This is where the raw data exists, not the metadata - that is entirely in Mysql.
HDFS is configured by the core-site.xml of the Hadoop client libraries required by Hive, not the hive-site.xml file
But I can't find those in filesystem.
Probably because those are HDFS paths, not places on your local filesystem
what is the meaning of this commands?
To create the default warehouse and temp scratch directories needed to store data to be used by Hive processes
