@QiangCai : Sending all index file info from executor to driver will bring serialization overhead? will it slowdown the load performance ? Also can the executors write directly into merge index file ? But If we acquire lock, I am afraid it will also slow down the load speed. Any idea which approach can be better ? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
