> Key: YARN-6721
> URL: https://issues.apache.org/jira/browse/YARN-6721

> As per https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt and given that container-executor is setuid, it should be compiled with stack checking if the compiler supports such features. (-fstack-check on gcc, -fsanitize=safe-stack on clang, -xcheck=stkovf on "Oracle Solaris Studio", others as we find them, ...)
