>
> 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++.)
