-----------------------------------
thanks [~nravi] that's very helpful.
> PageRank fails with unified memory manager
> ------------------------------------------
>
> Key: SPARK-11278
> URL: https://issues.apache.org/jira/browse/SPARK-11278
> Project: Spark
> Issue Type: Bug
> Components: GraphX, Spark Core
> Affects Versions: 1.5.1
> Reporter: Nishkam Ravi
> Assignee: Andrew Or
> Priority: Critical
> Attachments: executor_log_legacyModeTrue.html,
> executor_logs_legacyModeFalse.html

> PageRank (6-nodes, 32GB input) runs very slow and eventually fails with
> ExecutorLostFailure. Traced it back to the 'unified memory manager' commit
> from Oct 13th. Took a quick look at the code and couldn't see the problem
> (changes look pretty good). cc'ing [~andrewor14][~vanzin] who may be able to
> spot the problem quickly. Can be reproduced by running PageRank on a large
> enough input dataset if needed. Sorry for not being of much help here.
