[jira] [Created] (SPARK-11278) PageRank fails with unified memory manager

Nishkam Ravi created SPARK-11278:
------------------------------------

             Summary: PageRank fails with unified memory manager
                 Key: SPARK-11278
                 URL: https://issues.apache.org/jira/browse/SPARK-11278
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.5.2, 1.6.0
            Reporter: Nishkam Ravi


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.
