Thomas Marquardt commented on HADOOP-15659:
-------------------------------------------
One of the analytic platforms has a scenario where they disable the filesystem
cache and create many filesystems in a single process. It is also a
multi-tenant scenario, where they have multiple users running in the same
process. They rely on user's code to close the filesystem, and sometimes users
write bad code, and if we don't override finalize then the filesystem doesn't
get released and they hit an OOM condition. I agree with you that it is weird,
and unusual, but without this change their scenario does not work.
