FsShell -getmerge source file pattern is broken
-----------------------------------------------
Key: HADOOP-6387
URL: https://issues.apache.org/jira/browse/HADOOP-6387
Project: Hadoop Common
Issue Type: Bug
Components: fs
Reporter: Eli Collins
Fix For: 0.22.0
The FsShell -getmerge command doesn't work if the "source file pattern" matches files. See
below. If the current behavior is intended then we should update the help documentation and
java docs to match, but it would be nice if the user could specify a set of files in a directory
rather than just directories.
{code}
$ hadoop fs -help getmerge
-getmerge <src> <localdst>: Get all the files in the directories that
match the source file pattern and merge and sort them to only
one file on local fs. <src> is kept.
$ hadoop fs -ls
