IMPALA-13054: Avoid revisiting children in QueryStateExpanded

Avoids revisiting children in QueryStateExpanded due to duplicate
recursion. Since process_exec_profile visits children recursively, we
only want immediate children from GetChildren, not all children from
GetAllChildren.

Adjusts HDFS_SCAN_NODE test to look back at top of stack, rather than
depend on a specific depth that was caused by calling GetAllChildren
from the root.

This was identified by running the Impala E2E test suite with workload
management enabled, where
test_nested_types.py::TestMaxNestingDepth::test_max_nesting_depth took
multiple hours to run and blocked the FinishUnregisterQuery for other
tests.

Testing:
- Manual test with enable_workload_mgmt=true running
  test_max_nesting_depth.

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.
