Github user tgravescs commented on the pull request: https://github.com/apache/spark/pull/28#issuecomment-36255394 I personally like the way 4 spaces looks too. The style guide isn't clear on what its supposed to be. I'll assume it falls under the 4 space rule similar to functions: https://cwiki.apache.org/confluence/display/SPARK/Spark+Code+Style+Guide#SparkCodeStyleGuide-Indentation @pwendell - comment on the what the indentation is supposed to be? If 4 perhaps we should update the guide. Otherwise looks good to me. Thanks Sandy!
