> Implement ofs://: temp directory mount
> --------------------------------------
>
> Key: HDDS-2929
> URL: https://issues.apache.org/jira/browse/HDDS-2929
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Labels: pull-request-available
>
> Because of ofs:// filesystem hierarchy starts with volume then bucket, an
> application typically won't be able to write directly under a first-level
> folder, e.g. ofs://service-id1/tmp/. /tmp/ is a special case that we need to
> handle since that is the default location most legacy Hadoop applications
> write to for swap/temporary files. In order to address this, we would
> introduce /tmp/ as a client-side "mount" to another Ozone bucket.
> Note that the preliminary implementation would only allow for /tmp/ to be a
> mount but not any user-defined path.
> This depends on HDDS-2840 and HDDS-2928.
> Demo PR on my fork: https://github.com/smengcl/hadoop-ozone/pull/1
