SPARK-19276 ensured that FetchFailures do not get swallowed by other layers of exception handling, but it also meant that a killed task could look like a fetch failure. This is particularly a problem with speculative execution, where we expect to kill tasks as they are reading shuffle data. The fix is to ensure that we always check for killed tasks first. Added a new unit test which fails before the fix, ran it 1k times to check for flakiness. Full suite of tests on jenkins. Author: Imran Rashid <[email protected]> Closes apache#20987 from squito/SPARK-23816. (cherry picked from commit 10f45bb) Signed-off-by: Marcelo Vanzin <[email protected]>
