Jim Brennan commented on YARN-7796:
-----------------------------------
We ran into this same issue when running a container-executor that was compiled
on RHEL 6 on a RHEL 7 system. While we have verified that the patch in this
Jira does avoid the segmentation fault, we are concerned that the root cause of
the problem remains, and may bite us later.
The -fstack-check flag was added to the command line in YARN-6721
Based on my testing, a container-executor (without the patch from this Jira)
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.
[~grepas] - was this the case for you? Were you running a container-executor
that was compiled on an earlier redhat release?

> There is a relatively big (128K) buffer allocated on the stack in
> container-executor.c for the purpose of copying files. As indicated by the
> below gdb stack trace, this allocation can fail with SIGSEGV. This happens
> only on certain OS configurations - I can reproduce this issue on RHEL 6.9:
> {code:java}
> [Thread debugging using libthread_db enabled]
