Patrick Wendell commented on SPARK-2881:
----------------------------------------
Actually since this uses a static system property it might be better to just do
[~mridul]'s suggestion and keep this simple. One possibility is just a static
code block in the Snappy compression codec itself that sets it to a random sub
directory of /tmp/
> Snappy is now default codec - could lead to conflicts since uses /tmp

> Key: SPARK-2881
> URL: https://issues.apache.org/jira/browse/SPARK-2881
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.1.0
> Reporter: Thomas Graves
> Priority: Blocker
>
> I was using spark master branch and I ran into an issue with Snappy since its
> now the default codec for shuffle.
> The issue was that someone else had run with snappy and it created
> /tmp/snappy-*.so but it had restrictive permissions so I was not able to use
> it or remove it. This caused my spark job to not start.
> I was running in yarn client mode at the time. Yarn cluster mode shouldn't
> have this issue since we change the java.io.tmpdir.
> I assume this would also affect standalone mode.
> I'm not sure if this is a true blocker but wanted to file it as one at first
> and let us decide.
