Matthew Farrellee commented on SPARK-3685:
------------------------------------------
if you're going to go down this path the best (i'd say correct) way to
implement it is to have support from yarn - a way to tell yarn "i'm only going
to need X,Y,Z resources from now on" without giving up the execution container.
i bet there's a way to re-exec the jvm into a smaller form factor.
> Spark's local dir should accept only local paths

> Key: SPARK-3685
> URL: https://issues.apache.org/jira/browse/SPARK-3685
> Project: Spark
> Issue Type: Bug
> Components: Spark Core, YARN
> Affects Versions: 1.1.0
> Reporter: Andrew Or
>
> When you try to set local dirs to "hdfs:/tmp/foo" it doesn't work. What it
> will try to do is create a folder called "hdfs:" and put "tmp" inside it.
> This is because in Util#getOrCreateLocalRootDirs we use java.io.File instead
> of Hadoop's file system to parse this path. We also need to resolve the path
> appropriately.
> This may not have an urgent use case, but it fails silently and does what is
> least expected.
