One of the key use cases for Apache Drill is exploring and analyzing the raw data coming into Hadoop/NoSQL systems, using SQL. Along with meeting the table stakes for SQL-on-Hadoop, which is to achieve low latency performance at scale, Drill allows users to analyze the data without any ETL or upfront schema definitions. With this "schema-free" approach, you can get value from your data in minutes rather than spending weeks and months in data preparation.
