Effective in version 10.2.2, When you run a mapping on the Blaze engine to write data to an HDFS flat file target, the Data Integration Service creates the target files with the following naming convention:

<FileName>-P1, <FileName>-P2,....<FileName>-P100....<FileName>-PN

Previously, the target files were generated in the following format:

Target1.out, Target2.out....Target<PartitionNo>.out
