Alejandro Abdelnur commented on MAPREDUCE-5021:
-----------------------------------------------
Chris, I'm not sure I follow how the FileUtil method would help here. As I see
this JIRA the idea is to be able to do:
{code}
DistributedCache.addFileToClasspath(new Path("/user/tucu/lib/*"), jobConf);
{code}
Instead doing:
{code}
FileStatus[] files = fileStatus.listStatus(new Path("/user/tucu/lib"));
for (FileStatus[] file : files) {
if (file.getPath().toString().endsWith(".jar") {
DistributedCache.addFileToClasspath(file.getPath(), jobConf);
}
}
{code}
In other words, do the above logic within DistributedCache.

> Components: client, distributed-cache

> Reporter: Sandy Ryza

> As adding a directory of jars to the class path is a common use for the
> distributed cache it would be easier on API consumers if they were able to
> call a method that would add all the the files in a directory for them.
