             Summary: -fstack-check compilation flag causes binary incompatibility for container-executor between RHEL 6 and RHEL 7
                 Key: YARN-7857
                 URL: https://issues.apache.org/jira/browse/YARN-7857
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.0.0
            Reporter: Jim Brennan
            Assignee: Jim Brennan


The segmentation fault in container-executor reported in [YARN-7796]  appears to be due to a binary compatibility issue with the {{-fstack-check}} flag that was added in [YARN-6721]

Based on my testing, a container-executor (without the patch from [YARN-7796]) compiled on RHEL 6 with the -fstack-check flag always hits this segmentation fault when run on RHEL 7.  But if you compile without this flag, the container-executor runs on RHEL 7 with no problems.  I also verified this with a simple program that just does the copy_file.

I think we need to either remove this flag, or find a suitable alternative.
