Subject [jira] [Created] (SPARK-19045) irrelevant warning when creating a checkpoint dir
Date Sun, 01 Jan 2017 11:37:58 GMT
Assaf Mendelson created SPARK-19045:
---------------------------------------

             Summary: 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.
