Mridul Muralidharan commented on SPARK-1956: -------------------------------------------- shuffle consolidation MUST NOT be enabled - whether by default, or intentionally. In 1.0, it is very badly broken - we have a whole litany of fixes for it, before it was reasonably stable. Current plan is to contribute most of these back in 1.1 timeframe. > Enable shuffle consolidation by default > --------------------------------------- > > Key: SPARK-1956 > URL: https://issues.apache.org/jira/browse/SPARK-1956 > Project: Spark > Issue Type: Improvement > Components: Shuffle, Spark Core > Affects Versions: 1.0.0 > Reporter: Sandy Ryza > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
