[jira] [Resolved] (MAHOUT-1607) spark-shell:scheduler.DAGScheduler:
Failed to run fold at CheckpointedDrmSpark.scala:192
[ https://issues.apache.org/jira/browse/MAHOUT-1607?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrew Palumbo resolved MAHOUT-1607.
------------------------------------
Resolution: Not a Problem
This was likely caused by mismatched spark versions. Closing since there's no way to verify and this is currently not a problem:
{code}
