Subject [GitHub] spark issue #17955: [SPARK-20715] Store MapStatuses only in MapOutputTracker...
Date Mon, 15 May 2017 19:31:06 GMT
Github user JoshRosen commented on the issue:

    https://github.com/apache/spark/pull/17955
  
    @markhamstra, I think that the the `interruptThread = true` hardcoding may be orthogonal
to this PR's proposed changes: `interruptThread` affects how we carry out task cancellation,
not whether we attempt to cancel, so even if you set `interruptThread = false` you could still
effectively cancel redundant task attempts since those tasks would check the `interrupted`
flag in `TaskContext.isInterrupted` or via `InterruptibleIterator`.
