   Thanks for @jshmchenxi for the optimize work for spark on HDFS ( I just notice this and #2577,  it's impressive).
   
   Do we also need to parallelize the [SparkMicroBatchStream#planInputPartitions](https://github.com/apache/iceberg/blob/a100d2d5a06153674cdf97940039f3df68b5f9b8/spark3/src/main/java/org/apache/iceberg/spark/source/SparkMicroBatchStream.java#L140) in this PR ?
