Description

Default implementation sorts the array in ascending order of the files, a parameter can be added to current implementation so that it can sort in descending order as well.

Current impl:

Proposed:
public static boolean More ...copyMerge(FileSystem srcFS, Path srcDir, FileSystem dstFS, Path dstFile, boolean deleteSource, Configuration conf, String addString, boolean sort) throws IOException {
