Impala by-passes the Map-Reduce layer in Hadoop resulting in much faster query response times than Hive. Such as Plain Text, RCFIle, HBase, ORC, Also, it supports Metadata storage in RDBMS, Hive supports SQL like queries. It seems that Apache Hive with 2.68K GitHub stars and 2.63K forks on GitHub has more adoption than Apache Impala with 2.19K GitHub stars and 825 GitHub forks. Moreover,  for running queries on HDFS and Apache HBase, Impala is a wonderful choice. However, we have shown few differences between Hive and Impala technology but in practice, these are not two different competitors competing to show which one of them is the best. By using our site, you Hive offers an SQL – like language (HiveQL) with schema on reading and transparently converts querie… Ingestion is done as you say via hive - but impala will give you order(/s) of magnitude better read performance. Hive and Impala provide an SQL-like interface for users to extract data from Hadoop system. Some of the key features include HDFS file browser, Pig editor, Hive editor, Job browser, Hadoop shell, User admin permissions, Impala editor, Ozzie web interface and Hadoop API Access. With Impala, you can query data, whether stored in HDFS or Apache HBase – including SELECT, JOIN, and aggregate functions – in real time. So to clear this doubt, here is an article “HBase vs Impala: Feature-wise Comparison”. Apache Hive and Impala both are key parts of Hadoop system. Basics of Impala. Table was created in hive, loaded with data via insert overwrite table in hive (table is partitioned). Most Cloudera Hadoop clusters include both Hive and Impala which allow SQL access to data in the Hive metastore. Impala does not support complex types. b. Apache Hive and Impala. Some of the most powerful results come from combining complementary superpowers, and the “dynamic duo” of Apache Hive LLAP and Apache Impala, both included in Cloudera Data Warehouse, is further evidence of this. Resolution Days 2021 - Step Into a New You This Year! Impala uses daemon processes and is better suited to interactive data analysis.
