> 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.
