IMPALA-13024: Ignore slots if using default pool and empty group

Slot based admission should not be enabled when using default pool.
There is a bug where coordinator-only query still does slot based
admission because executor group name set to
ClusterMembershipMgr::EMPTY_GROUP_NAME ("empty group (using coordinator
only)"). This patch adds check to recognize coordinator-only query in
default pool and skip slot based admission for it.

Testing:
- Add BE test AdmissionControllerTest.CanAdmitRequestSlotsDefault.
- In test_executor_groups.py, split test_coordinator_concurrency to
  test_coordinator_concurrency_default and
  test_coordinator_concurrency_two_exec_group_cluster to show the
  behavior change.
- Pass core tests in ASAN build.

Welcome to Impala

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:

More about Impala

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.

If you are interested in contributing to Impala as a developer, or learning more about Impala's internals and architecture, visit the Impala wiki.

Supported Platforms

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.

Supported OS Distributions

Impala runs on Linux systems only. The supported distros are

  • Ubuntu 16.04/18.04
  • CentOS/RHEL 7/8

Other systems, e.g. SLES12, may also be supported but are not tested by the community.

Export Control Notice

This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.

Build Instructions

See Impala's developer documentation to get started.

Detailed build notes has some detailed information on the project layout and build.
