What are different types of schemas in hbase/hive?

[#1]

I would like to know the schemas in hbase

Please edit your questions with some additional information as this is not enough for the community to try to help you. Are you wondering about any "sys catalog" styled information that HBase maintains internally?

If you are asking about "classic schemas/database", then Hive has this with normal SQL commands such as "CREATE DATABASE xyz" and "USE xyz" as well as allows you to prefix your tables with the schema/database name.

HBase has a concept called namespaces. Of course, now looking back at https://community.hortonworks.com/questions/60379/how-to-create-namespace-in-hbase.html it seems you already asked that question.

Take this as constructive criticism, not as whining; you will get much better responses if you can describe your questions/concerns better than one-liners. Good luck and happy Hadooping!
