IMPALA-12833: Enabled 'catalogd_ha_reset_metadata_on_failover' by default The standby catalogd may have stale metadata for some reason, like event processor could have hung or could be just behind in processing events. Also the standby catalogd doesn't get invalidate requests from coordinators so we should probably reset its metadata when it becomes active to avoid stale metadata. This patch set the default value of catalog server starting flag 'catalogd_ha_reset_metadata_on_failover' as true so that catalogd will reset its metadata when it becomes active. Also makes the flag as hidden option. Testing: - Looped to run unit-tests for catalog HA and statestore HA without failure. - Passed core tests Change-Id: Ibc7c529f34b70734a700ac0d9d58b7e5b0215f8d Reviewed-on: http://gerrit.cloudera.org:8080/21051 Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Reviewed-by: Michael Smith <michael.smith@cloudera.com> Reviewed-by: Abhishek Rawat <arawat@cloudera.com>
Lightning-fast, distributed SQL queries for petabytes of data stored in open data and table formats.
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:
The fastest way to try out Impala is a quickstart Docker container. You can try out running queries and processing data sets in Impala on a single machine without installing dependencies. It can automatically load test data sets into Apache Kudu and Apache Parquet formats and you can start playing around with Apache Impala SQL within minutes.
To learn more about Impala as a user or administrator, or to try Impala, please visit the Impala homepage. Detailed documentation for administrators and users is available at Apache Impala documentation.

Impala only supports Linux at the moment. Impala supports x86_64 and has experimental support for arm64 (as of Impala 4.0). Impala Requirements contains more detailed information on the minimum CPU requirements.
Impala runs on Linux systems only. The supported distros are
Other systems, e.g. SLES12, may also be supported but are not tested by the community.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
