@tnachen I copy-pasted the Spark configuration docs in my previous
comments. Here's what I meant by other parameters though:
- `spark.local.dir` Directory to use for "scratch" space in Spark
- ` SPARK_LOCAL_DIRS` - In Spark 1.0 and later this will override the
pervious one
So, yes, the order of evaluation is one of the problems. Is there a way to
configure `MESOS_DIRECTORY` itself? People may want to put *multiple*
directories on different volumes, for performance. Since `MESOS_DIRECTORY` is
just one, this won't be possible anymore.
It's different in Yarn because Yarn already has this concept: it gives you
*several* scratch directories, precisely for this purpose.
The other (big) problem is dynamic allocation w/ external shuffle service
(but we can test and only use `MESOS_DIRECTORY` when the shuffle service is
disabled). See my comments on
[SPARK-9708](https://issues.apache.org/jira/browse/SPARK-9708)
