IMPALA-12835: Fix event processing without hms_event_incremental_refresh_transactional_table If hms_event_incremental_refresh_transactional_table is false, then for non-partitioned ACID tables Impala needs to rely on alter table event to detect INSERTs in Hive. This patch changes the event processor to not skip reloading files when processing the alter table event for this specific type of table (even if the changes in the table look trivial). Testing: - added a simple regression test Change-Id: I137b289f0e5f7c9c1947e2a3b30258c979f20987 Reviewed-on: http://gerrit.cloudera.org:8080/21116 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@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.
