Apache Tez is the next generation Hadoop query processing framework and execution engine written on top of YARN. Tez is a replacement for the MapReduce application that supports a range of performance features that radically improve query latency in Hadoop. This improvement in query performance enables the use of Hadoop for interactive queries by business analysts and data scientists. With Tez, Hadoop provides both interactive and batch queries.
Prerequisites
