default
[ https://issues.apache.org/jira/browse/SPARK-1956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14221453#comment-14221453 ]
Sandy Ryza commented on SPARK-1956:
-----------------------------------
This is of smaller importance now that sort-based shuffle is the default, but how do we feel about turning this on by default now? [~mridulm80], have the issues you're aware of been resolved?

> The only drawbacks are on ext3, and most everyone has ext4 at this point. I think it's better to aim the default at the common case.
