Impala and Shark Benchmark

We have created Impala and Shark cluster on Amazon EC2 m3.2xlarge machine with 30GB RAM. We loaded a 50 GB dataset into the system and run queries on top of it to benchmark the performance between the two systems:

Shark is a large-scale data warehouse system for Spark designed to be compatible with Apache Hive. It can execute Hive QL queries up to 100 times faster than Hive without any modification to the existing data or queries. Shark supports Hive’s query language, metastore, serialization formats, and user-defined functions, providing seamless integration with existing Hive deployments and a familiar, more powerful option for new ones.

Cloudera Impala is an open source Massively Parallel Processing (MPP) query engine that runs natively on Apache Hadoop. The Apache-licensed Impala project brings scalable parallel database technology to Hadoop, enabling users to issue low-latency SQL queries to data stored in HDFS and Apache HBase without requiring data movement or transformation. Impala is integrated from the ground up as part of the Hadoop ecosystem and leverages the same flexible file and data formats, metadata, security and resource management frameworks used by MapReduce, Apache Hive, Apache Pig and other components of the Hadoop stack.

The video contains details of the performance statistics of both systems.
