spark-distcp sourcefile destfile fails

[gquintana]

When source and destination are files not directories, Spark DistCP fails:

2022-02-04 15:58:43,344 [main] INFO  org.apache.spark.scheduler.DAGScheduler - Job 1 finished: isEmpty at FileListUtils.scala:256, took 0.040579 s
Exception in thread "main" java.lang.RuntimeException: Collisions found where multiple source files lead to the same destination location; check executor logs for specific collision detail.

It fails in v0.2.5, it used to work in 0.2.2

I don't have any logs starting with The following files will collide on destination file before
