> 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]
> main : command provided 0
> main : run as user is ***
> main : requested yarn user is ***
> Program received signal SIGSEGV, Segmentation fault.
