Sean Owen commented on SPARK-19045:
-----------------------------------
I get it, but it's not worth this complexity to check these cases just to hide
a message that's only a warning.
> irrelevant warning when creating a checkpoint dir
> -------------------------------------------------
>
> Key: SPARK-19045
> URL: https://issues.apache.org/jira/browse/SPARK-19045
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.0
> Reporter: Assaf Mendelson
> Priority: Trivial
>
> When I do:
> sc.setCheckpointDir("/mydir") I get a warning:
> 17/01/01 06:26:42 WARN SparkContext: Spark is not running in local mode,
> therefore the checkpoint directory must not be on the local filesystem.
> Directory '/mydir' appears to be on the local filesystem.
> This occurs even though I use a single computer with local filesystem (using
> spark standalone). Reading the code it seems the same error would occur if I
> would use a cluster and an NFS share.
> Checkpoint should work on a local directory as long as there is a single node
> (even when using a resource manager rather than a single node) and should
> work in a cluster with locally mounted NFS share.
