View entire discussion ( 5 comments) From the experiment, we conclude as follows: Impala runs faster than Hive on MR3 on short-running queries that take less than 10 seconds. Hive & Pig answers queries by running Mapreduce jobs.Map reduce over heads results in high latency. Cloudera’s Impala brings Hadoop to SQL and BI 25 October 2012, ZDNet. So we had hive that is capable enough to process these big data queries, so what made the existence of impala we will try to find the answer for this.

This one tries to explain why Impala is faster than Hive even now Hives has columnar store and Tez. Cloudera's a data warehouse player now 28 August 2018, ZDNet. Thanks. Why Impala is faster than Hive in query processing We have mentioned many times in this book that Impala is a very fast distributed data-processing framework, so you might want to know how Impala achieves such speed or what is behind Impala that makes it so fast.
