Konstantin Boudnik commented on BIGTOP-997:
-------------------------------------------
Ok, the problem with the bug is this:
- as a part of BIGTOP-895 everything that say {{supergroup}} is now replaced
with whatever coming from {{DFSConfigKeys.DFS_PERMISSIONS_SUPERUSERGROUP_KEY}}
- by default it is set to be group {{hadoop}}
- when {{TestCLI}} creates files and directories under {{/tmp}} they are
inherit group settings from the parent directory (which is {{hadoop}} normally)
- when directory or file creation happens with a relative path (e.g. {{fs
-mkdir -p dir1}} the new directory is getting created under user's home e.g.
{{/user/jenkins}} which is likely to have {{supergroup}} group credentials.
This eventually leads to the situation where we see the bug if the test is ran
under user belonging to group {{supergroup}}. One way to fix it is to make sure
that user's group is {{hadoop}}. Another way is to have smarter
{{expandCommand}} in the test.
