> # fs.s3a.buffer.dir defaults to hadoop.tmp.dir which is /tmp or similar
> # we use this for storing file blocks during upload
> # staging committers use it for all files in a task, which can be a lot more
> # a lot of systems don't clean up /tmp until reboot -and if they stay up for
> a long time then they accrue files written through s3a staging committer from
> spark containers which fail
> Fix: use ${env.LOCAL_DIRS:-${hadoop.tmp.dir}}/s3a as the option so that if
> env.LOCAL_DIRS is set is used over hadoop.tmp.dir. YARN-deployed apps will
> use that for the buffer dir. When the app container is destroyed, so is the
> directory.
