Gera Shegalov commented on HADOOP-12747:
----------------------------------------
GOP=Generic Options Parser but there is room for [~cnauroth]'s interpretation.
Your approach touches more code I would think, and keeps the annoying problem
that there are tons of entries under cache.files from the *same* dir. Thus
going from fat jar to bundle results in fat conf so to speak.
> support wildcard in libjars argument

> There is a problem when a user job adds too many dependency jars in their
> command line. The HADOOP_CLASSPATH part can be addressed, including using
> wildcards (\*). But the same cannot be done with the -libjars argument. Today
> it takes only fully specified file paths.
> We may want to consider supporting wildcards as a way to help users in this
> situation. The idea is to handle it the same way the JVM does it: \* expands
> to the list of jars in that directory. It does not traverse into any child
> directory.
> Also, it probably would be a good idea to do it only for libjars (i.e. don't
> do it for -files and -archives).
