      Description

      As a DataFrame author, I can elect to bucketize my output without involving Hive or HMS, so that my hive-less environment can benefit from this query-optimization technique. 

       

      https://issues.apache.org/jira/browse/SPARK-19256?focusedCommentId=16345397&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16345397 identifies this as a shortcoming with the umbrella feature in provided via SPARK-19256.

       

      In short, relying on Hive to store metadata precludes environments which don't have/use hive from making use of bucketization features.
