--------------------------------------
Summary: BasicBlockFetchIterator#next should log when it gets stuck
Key: SPARK-2717
URL: https://issues.apache.org/jira/browse/SPARK-2717
Project: Spark
Issue Type: Bug
Reporter: Patrick Wendell
Priority: Blocker
If this is stuck for a long time waiting for blocks, we should log what nodes
it is waiting for to help debugging. One way to do this is to call take() with
a timeout (e.g. 60 seconds) and when the timeout expires log a message for the
blocks it is still waiting for. This could all happen in a loop so that the
wait just restarts after the message is logged.
