I receive the following error message:

Answer 1

This is because of the lack of permission to the user aseema in hdfs. Follow the steps below.

Login as hduser and perform the following operations (from the logs, it seems hduser is a superuser)

hadoop fs -mkdir -p /user/hive/warehouse
hadoop fs -mkdir /tmp
hadoop fs -chmod -R 777 /user/hive
hadoop fs -chmod 777 /tmp

After this, try executing the create database statement from aseema user.

Answer 2

If you are running from Local Mode then you should run this command from hdfs user:

su hdfs

Then change the permission like below if you want:

hdfs dfs -chown -R <username_of_new_owner> /user
