Subject [jira] [Commented] (SPARK-19045) irrelevant warning when creating a checkpoint dir
Date Mon, 02 Jan 2017 09:07:58 GMT

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.

> 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.
