    [ https://issues.apache.org/jira/browse/SPARK-16599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15832569#comment-15832569
] 

Drew Robb commented on SPARK-16599:
-----------------------------------

I encountered an identical exception when using a singleton spark session. For me, I was able
to resolve the issue by ensuring all objects that used the singleton spark session did a `import
spark.implicits._`, even if that particular import was not necessary for compiling.
