To @lihao712 , Apache Spark (3.0.2+) uses version 1 by default (via SPARK-33019) due to the correctness issue of version 1. > As far as I know, after Hadoop 2.7, the algorithm for checking the task commit path is version 2, and the version 1 implementation performs poorly in practice. For tasks with a large number of files, under the algorithm version 2, how can we ensure that there won't be two task commit files for the same partition existing simultaneously in the final directory? - #29895 -- This is an automated message from the Apache Git Service.
