IMPALA-12782: Show info of the event processing in /events webUI The /events page of catalogd shows the metrics and status of the event-processor. This patch adds more info in this page, including - lag info - current event batch that's being processed See the screenshot attached in the JIRA for how it looks like. Also moves the error message to the top to highlight the error status. Fixes the issue of not updating latest event id when event processor is stopped. Also fixes the issue of error message not cleared after global INVALIDATE METADATA. Adds a debug action, catalogd_event_processing_delay, to inject a sleep while processing an event. So the web page can be captured more easily. Also adds a missing test for showing the error message of event-processing in the /events page. Tests: - Add e2e test to verify the content of the page.

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.
