IMPALA-9296: Move AuxErrorInfo to StatefulStatus This patch moves AuxErrorInfoPB from FragmentInstanceExecStatusPB to StatefulStatusPB. This is necessary because if the report with the AuxErrorInfoPB is dropped (e.g. due to backpressure at the Coordinator or a flaky network), the next report won't contain the AuxErrorInfoPB, and the error info will be lost. StatefulStatus solves this by detecting any reports that may not have been received by the Coordinator, and re-transmitting any StatefulStatuses that were not successfully delivered. This change also makes the setting of AuxErrorInfoPB stateful, so that the error info only shows up in one report and is then dropped from the RuntimeState.

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. |
