IMPALA-8065: Add OS distribution name in OSInfo Before this change OsInfo::DebugString() would print two lines: - OS version: the long name of the Linux kernel from /proc/version - Clock: the type of clock used After this change OsInfo::DebugString() will print three lines: - OS distribution: the short name of the OS release. If Docker is being used this is the name of the Container OS. - OS version: the long name of the Linux kernel from /proc/version. If Docker is being used this is the description of the Host Kernel. - Clock: the type of clock used. Tested locally, the displayed OS Info in Ubuntu16 dev box is: OS distribution: Ubuntu 16.04.6 LTS OS version: Linux version 4.15.0-65-generic (buildd@lcy01-amd64-017) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10)) Clock: clocksource: 'tsc', clockid_t: CLOCK_MONOTONIC Also checked with diff OS in docker: centos, redhat, ubuntu, oracle, debian to make sure /etc/os-release exists and PRETTY_NAME in that file. Each OS picked one version to test. Specially for centos6 and redhat6, which have redhat-release instead of os-release, copied redhat-release into Ubuntu16 dev box and verified os version in mini-cluster. Added new backend test os-info-test.cc.

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.
Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:
To learn more about Impala as a business user, or to try Impala live or in a VM, please visit the Impala homepage.
If you are interested in contributing to Impala as a developer, or learning more about Impala's internals and architecture, visit the Impala wiki.
Impala only supports Linux at the moment.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
See bin/bootstrap_build.sh.
Impala can be built with pre-built components or components downloaded from S3. The components needed to build Impala are Apache Hadoop, Hive, HBase, and Sentry. If you need to manually override the locations or versions of these components, you can do so through the environment variables and scripts listed below.
Location | Purpose |
---|---|
bin/impala-config.sh | This script must be sourced to setup all environment variables properly to allow other scripts to work |
bin/impala-config-local.sh | A script can be created in this location to set local overrides for any environment variables |
bin/impala-config-branch.sh | A version of the above that can be checked into a branch for convenience. |
bin/bootstrap_build.sh | A helper script to bootstrap some of the build requirements. |
bin/bootstrap_development.sh | A helper script to bootstrap a developer environment. Please read it before using. |
