    [SPARK-9244] Increase some memory defaults · fe26584a
    Matei Zaharia authored
    There are a few memory limits that people hit often and that we could
    make higher, especially now that memory sizes have grown.
    
    - spark.akka.frameSize: This defaults at 10 but is often hit for map
      output statuses in large shuffles. This memory is not fully allocated
      up-front, so we can just make this larger and still not affect jobs
      that never sent a status that large. We increase it to 128.
    
    - spark.executor.memory: Defaults at 512m, which is really small. We
      increase it to 1g.
