IMPALA-6308: Fix bad Status() usage in data-stream-sender.cc Previously, DataStreamSender::FlushAndSendEos() makes some wrong assumption about the format string of the error status returned from DoTransmitDataRpc(). In particular, it assumes that the format string has exactly one substitution argument. This is a pretty bad assumption as new types of errors could be returned from DoTransmitDataRpc() and they can take different numbers of substitution arguments. Recent changes in the format string TErrorCode::RPC_RECV_TIMEOUT exposed this bug. This change fixes the problem by removing this bad usage of Status() in data-stream-sender.cc Change-Id: I1cc04db670069a7df484e2f2bafb93c5315b9c82 Reviewed-on: http://gerrit.cloudera.org:8080/8817 Reviewed-by: Tim Armstrong <tarmstrong@cloudera.com> Tested-by: Impala Public Jenkins
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:
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.
Impala only supports Linux at the moment.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
See bin/bootstrap_build.sh.
Impala can be built with pre-built components, downloaded from S3, or can be built with an in-place toolchain located in the thirdparty directory (not recommended). 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.
Location | Purpose |
---|---|
bin/impala-config.sh | This script must be sourced to setup all environment variables properly to allow other scripts to work |
bin/impala-config-local.sh | A script can be created in this location to set local overrides for any environment variables |
bin/impala-config-branch.sh | A version of the above that can be checked into a branch for convenience. |
bin/bootstrap_build.sh | A helper script to bootstrap some of the build requirements. |
bin/bootstrap_development.sh | A helper script to bootstrap a developer environment. Please read it before using. |
be/build/ | Impala build output goes here. |
be/generated-sources/ | Thrift and other generated source will be found here. |
Environment variable | Default value | Description |
