Builds off #569 I could also make a PR that works off spark-25299 branch, but it would be a lot of merge conflicts @mccheah @ifilonenko for initial review |

There was a problem hiding this comment.
I think this has to be taskContext.taskAttemptId() to deal w/ multiple retries for the same stage. attemptNumber() will deal with speculative execution, but if you've got a zombie taskset still running a shuffle map task, and then another taskset is launched for the same stage, they'll both have attemptNumber() == 0
