This can lead to pathological cases where your > first partition is empty and rest have data. This unfortunately can happen > with skewed data. Empirically observed it's better to make few roundtrips > instead of potentially killing driver with big collect -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
