Description

batch build partial statistics file path is .../statistics/statistics_{shardID}

optimize job partial statistics file path is .../statistics/cuboid_statistics.seq_{shardID}

And in SaveStatistics step, it use "statistics" as prefix to filter files in hdfs, so to make it consistent, change the optimize job statistics file name to .../statistics/statistics_{shardID}
