Subject [jira] [Commented] (SPARK-23060) RDD's apply function
Date Fri, 12 Jan 2018 17:58:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-23060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16324292#comment-16324292
] 

Sean Owen commented on SPARK-23060:
-----------------------------------

Why not just write foo(rdd)? Is this necessary for some kind of interoperability? (e.g. Scala
implements Function objects with an apply method)
