------------------------------------
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.
