Subject [jira] [Commented] (YARN-7857) -fstack-check compilation flag causes binary incompatibility for container-executor between RHEL 6 and RHEL 7

Jim Brennan commented on YARN-7857:
-----------------------------------

Thanks [~miklos.szegedi@cloudera.com]! That is a good suggestion. I will need to do some more
investigation - I would think the key factor is the GCC version, not the OS version.

> 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.
