      Description

      SPARK-25871 introduced a regression in the streaming WAL – it no longer makes all the parent dirs, so you may see an exception like this in cases that used to work:

      18/11/09 03:31:48 ERROR util.FileBasedWriteAheadLog_ReceiverSupervisorImpl: Failed to write to write ahead log after 3 failures
