------------------------------------
Summary: Compile thirdparty toolchain libs with TSAN
Key: IMPALA-9567
URL: https://issues.apache.org/jira/browse/IMPALA-9567
Project: IMPALA
Issue Type: Sub-task
Reporter: Sahil Takiar
>From Todd L. on an email chain about enabling TSAN:

One point, though, is that for TSAN to work well, you need to instrument
thirdparty libs as well, so we'd need to start from native-toolchain and
work our way up.
{quote}
Currently, all thirdparty libs from Impala's native-toolchain are release
builds, we need to have TSAN-enabled builds (e.g. compile with
{{fsanitize=thread}}) in order to get TSAN to work for thirdparty libs as well.
We enabled the TSAN flag {{ignore_noninstrumented_modules}} to suppress all the
TSAN warnings from the JVM. So we currently can't use TSAN for any code that
cross third-party libs (e.g. we probably can't catch any data races that
involve {{boost::mutex}}).
