--------------------------------------
Summary: single_node_perf_run.py should execute subcommands with a
clean environment
Key: IMPALA-15042
URL: https://issues.apache.org/jira/browse/IMPALA-15042
Project: IMPALA
Issue Type: Task
Components: Infrastructure
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
single_node_perf_run.py executes using impala-python3 and then runs
buildall.sh. impala-python3 sets LD_LIBRARY_PATH in the environment. If the
system libstdc++ is newer than the toolchain libstdc++, then using this
LD_LIBRARY_PATH is incompatible with running system binaries, which need the
newer libstdc++. To avoid this issue, single_node_perf_run.py should run the
subcommands without inheriting the environment. This prevents other issues as
well.
(An alternative is to only include the toolchain GCC home on the
LD_LIBRARY_PATH if the toolchain libstdc++ is newer than system libstdc++.)
