> An empty token (e.g. "a.jar,,b.jar") in the -libjars option causes the current working
directory to be recursively localized.
> Here's an example of this in action (using Hadoop 2.2.0):
> {code}
> # create a temp directory and touch three JAR files
> mkdir -p tmp/path && cd tmp && touch a.jar b.jar c.jar path/d.jar
> # Run an example job only specifying two of the JARs.
> # Include an empty entry in libjars.
> hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar
pi -libjars a.jar,,c.jar 2 1000000000
> # As the job is running examine the localized directory in HDFS.
> # Notice that not only are the two JAR's specified in libjars copied,
> # but in addition the contents of the working directory are also recursively copied.
> $ hadoop fs -lsr /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars
> /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars/a.jar
> /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars/c.jar
> /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars/tmp
> /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars/tmp/a.jar
> /tmp/hadoop-yarn/staging/aholmes/.staging/job_1404752711144_0018/libjars/tmp/b.jar
