The main difference between Hive and Impala is that the Hive is a data warehouse software that can be used to access and manage large distributed datasets built on Hadoop while Impala is a massive parallel processing SQL engine for managing and analyzing data stored on Hadoop.. Hive is an open source data warehouse system to query and analyze large data sets stored in Hadoop files. It would be definitely very interesting to have a head-to-head comparison between Impala, Hive on Spark and Stinger for example. Apache Hive is fault tolerant. Hive supports complex types. Checkout Hadoop Interview Questions. Hive is batch based Hadoop MapReduce. Impala has been shown to have performance lead over Hive by benchmarks of both Cloudera (Impala’s vendor) and AMPLab. Apache Hive is an effective standard for SQL-in-Hadoop. Impala is more like MPP database. Hive vs Impala – SQL War in the Hadoop Ecosystem Last Updated: 30 Apr 2017.
