The possible reason could be, you logged into hive shell from different location and hence the default derby meta store changed.Kindly check below screen shots:


Step 1) I have logged into hive shell from /home/edureka/Desktop


Now  I have created a db named sumit.




After this, I exited from hive shell and re logged in to it from a different location, ie; /home/edureka.


Here, show databases will not show the database sumit that we created because the derby metastore changed.




But the same database,ie; sumit resides in hdfs.




Hope this resolves your query

In case of any further issue,feel free to revert.
