Hadoop has continued to grow and develop ever since it was introduced in the market 10 years ago. Every new release and abstraction on Hadoop is used to improve one or the other drawback in data processing, storage and analysis. Apache Hive was introduced by Facebook to manage and process the large datasets in the distributed storage in Hadoop. Apache Hive is an abstraction on Hadoop MapReduce and has its own SQL like language HiveQL. Cloudera Impala was developed to resolve the limitations posed by low interaction of Hadoop Sql. Cloudera Impala provides low latency high performance SQL like queries to process and analyze data with only one condition that the data be stored on Hadoop clusters.
