Eric Yang commented on YARN-8922:

[~rkanter] Thank you for the patch.  I get a segmentation fault with patch 001 when running
test-container-executor as normal user.

[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:3.3.0-SNAPSHOT:cmake-test

> YARN-8448 attempted to fix the {{test-container-executor}} C test to be able to run
as root.  The test claims that it should be possible to run as root; in fact, there are some
tests that only run if you use root.  
> One of the fixes was to change the permissions of the test's config dir to 0777 from
0755.  The problem was that the directory was owned by root, but then other users would need
to write files/directories under it, which would fail with 0755.  YARN-8448 fixed this by
making it 0777.  However, this breaks running cetest because it expects the directory to be
0755, and it's run afterwards.
> The proper fix for all this is to leave the directory at 0755, but to make sure it's
owned by the "nodemanager" user.  Confusingly, in {{test-container-executor}}, that appears
to be the {{username}} and not the {{yarn_username}} (i.e. {{username}} is the user running
the NM while {{yarn_username}} is just some user running a Yarn app).
