Hi, @Zhangshunyu, in your HDFS config, did you set `dfs.provided.overreplication.factor` with a number larger than 0? This property is used to control the number of cached block (cached to HDFS from remote storage). If it is set to 0 (default setting), the redundant cached block will be deleted by HDFS, which can trigger replica not found exception. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
