IMPALA-7984: Port runtime filter from Thrift RPC to KRPC

Previously the aggregation and propagation of a runtime filter in Impala is
implemented using Thrift RPC, which suffers from a disadvantage that the number
of connections in a cluster grows with both the number of queries and cluster
size. This patch ports the functions that implement the aggregation and
propagation of a runtime filter, i.e., UpdateFilter() and PublishFilter(),
respctively, to KRPC, which requires only one connection per direction between
every pair of hosts, thus reducing the number of connections in a cluster.

In addition, this patch also incorporates KRPC sidecar when the runtime filter
is a Bloom filter. KRPC sidecar eliminates the need for an extra copy of the
Bloom filter contents when a Bloom filter is serialized to be transmitted and
hence reduces the serialization overhead. Due to the incorporation of KRPC
sidecar, a SpinLock is also added to prevent a BloomFilter from being
deallocated before its associated KRPC call finishes.

Two related BE tests bloom-filter-test.cc and bloom-filter-benchmark.cc are
also modified accordingly because of the changes to the signatures of some
functions in BloomFilter.

Testing:
This patch has passed the exhaustive tests.

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

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:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase and Amazon S3.
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate CPU-efficient code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including the Apache Parquet project.
  • Apache-licensed, 100% open source.

More about Impala

To learn more about Impala as a business user, or to try Impala live or in a VM, please visit the Impala homepage.

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.

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 bin/bootstrap_build.sh.

Detailed Build Notes

Impala can be built with pre-built components or components downloaded from S3. The components needed to build Impala are Apache Hadoop, Hive, HBase, and Sentry. If you need to manually override the locations or versions of these components, you can do so through the environment variables and scripts listed below.

Scripts and directories
LocationPurpose
bin/impala-config.shThis script must be sourced to setup all environment variables properly to allow other scripts to work
bin/impala-config-local.shA script can be created in this location to set local overrides for any environment variables
bin/impala-config-branch.shA version of the above that can be checked into a branch for convenience.
bin/bootstrap_build.shA helper script to bootstrap some of the build requirements.
bin/bootstrap_development.shA helper script to bootstrap a developer environment. Please read it before using.
