In this post I will show you how to check Cloudera" Impala" version using CLI. It’s very easy and only what you need is the access to Impala" of course 🙂



Apache Impala" is an open-source distributed SQL query engine that is designed to process large amounts of data stored in Apache Hadoop" and other data storage systems. It allows users to issue SQL" queries to the data stored in these systems, and provides fast response times by executing the queries in parallel across a cluster of machines.

Impala is designed to be compatible with the Hive" Query Language (HQL), which is based on SQL", and it supports a wide range of data types and functions. It can be used to query data stored in various formats, including text files, Parquet" files, and Avro" files.

Impala" is often used in scenarios where fast query performance is important, such as in data warehousing and business intelligence applications. It can be integrated with various BI tools, such as Tableau and MicroStrategy, to allow users to analyze and visualize data stored in Hadoop.

Impala is developed and maintained by Cloudera", a provider of software and services for the Hadoop ecosystem. It is available as part of the Cloudera" Distribution for Hadoop (CDH) and can be downloaded and installed on a Hadoop cluster.


Impala-shell is a command-line interface" (CLI) for running Impala" SQL" commands and queries. It is included as part of the Apache Impala" distribution and can be used to interact with Impala from the command line" or from a script.

To use client, you will need to have Impala" installed and running on your system. You can then open" a terminal window and type impala-shell to start the shell". You will be prompted to enter your Impala" hostname" and port number, and you can then enter Impala" SQL" commands and queries at the prompt.

Impala-shell supports many of the same commands as the MySQL" CLI, such as SHOW TABLES and DESCRIBE. It also includes some Impala-specific commands, such as INVALIDATE METADATA, which is used to refresh the Impala" catalog with new or updated data.

Client can be used to perform a wide range of tasks, such as creating and dropping tables, loading data into Impala", and running queries to analyze data. It is a useful tool for interacting with Impala", especially for users who are comfortable using a command-line interface".

Impala Releases

Here is a list of the major releases of Apache Impala", along with their release dates:

Note that these are the major releases of Impala", and that there have been numerous minor releases and point releases between each major release. You can find more information about the history of Impala" and the various releases on the Apache Impala" website.

Command Line Interface (CLI)

A command line interface" (CLI) allows a user" to interact with a computer program by typing commands and receiving text-based output. CLIs are text-based interfaces that use a keyboard to enter commands, in contrast to a graphical user" interface (GUI) which uses a mouse and icons.

They are often used in operating systems and servers to manage files, install software, and configure system settings, and are also commonly used in programming" languages and database" systems to execute commands and scripts.

A user" typically uses a terminal window or command prompt to enter a command, which is then passed to the program to be executed and produce output.

CLIs can be more efficient than GUI-based interfaces for tasks that are performed frequently or require a high level of precision, and are often preferred by experienced users who are comfortable typing commands and do not need the visual cues of a GUI.

How To Check Cloudera Impala Version?

To check the Cloudera Impala version you can use command line interface" (CLI).

To do this you must login" to Cloudera" Cluster Edge Node for instance and then, connect to Impala" by impala-shell execute the following command on linux":

$ impala-shell --ssl -k -i <impala_host>

Starting Impala Shell using Kerberos authentication
Using service name 'impala'
SSL is enabled. Impala server certificates will NOT be verified (set --ca_cert to change)
Opened TCP connection to <impala_host>
Connected to <impala_host>
Server version: impalad version 2.12.0-cdh5.16.2 RELEASE (build ac3e9ba40b13332a70269114f40adf5c8e6d303b)
Welcome to the Impala shell.
(Impala Shell v2.12.0-cdh5.16.2 (ac3e9ba) built on Mon Nov 16 23:57:13 PST 2020)

In my case the version is: Impala" 2.12.0-cdh5.16.2

Already logged Into Cloudera Impala?

If you are already logged into Impala" you can just run the version() command to get the all information about you Cloudera" Impala" version.

[<impala_host>] > version();

Shell version: Impala Shell v2.12.0-cdh5.16.2 (ac3e9ba) built on Mon Nov 16 23:57:13 PST 2020
Server version: impalad version 2.12.0-cdh5.16.2 RELEASE (build ac3e9ba40b13332a70269114f40adf5c8e6d303b)

Check Impala Version Using SQL

You can also run the SELECT version() query to check the version. This will display the Impala" version as well as the version of the underlying Apache Hadoop distribution.

SELECT version();


Now you know how to check Cloudera Impala version and use this information to provide correct dependency when you’re creating the applications which will be running on the cluster.
