What query language does Hadoop use?

.
Likewise, people ask, what is SQL on Hadoop?
SQL on Hadoop is a type of analytical application tool — the SQL implementation on the Hadoop platform, which combines standard SQL-style querying of structured data with the Hadoop data framework.
Subsequently, question is, what is the difference between Hadoop and SQL? SQL only work on structured data, whereas Hadoop is compatible for both structured, semi-structured and unstructured data. SQL is based on the Entity-Relationship model of its RDBMS, hence cannot work on unstructured data. Hadoop vs SQL database – of course, Hadoop is better.
Keeping this in view, which offers a query like language for data manipulation in Hadoop?
Hive is often used because of its SQL like query language is used as the interface to an Apache Hadoop based data warehouse.
What language does hive use?
SQL
