[jira] [Commented] (SPARK-5569) Checkpoints cannot reference
classes defined outside of Spark's assembly
[ https://issues.apache.org/jira/browse/SPARK-5569?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15379976#comment-15379976 ]
Michael Li commented on SPARK-5569:
-----------------------------------
It seems the PR (https://github.com/apache/spark/pull/8955) has been merged to master. Why is this issue still open? The reason I'm asking is that I saw this issue once in our spark 1.6.1 streaming project. I am wondering which version the PR was merged.
