------------------------------------
Summary: support wildcard in libjars argument
Key: HADOOP-12747
URL: https://issues.apache.org/jira/browse/HADOOP-12747
Project: Hadoop Common
Issue Type: New Feature
Components: util
Reporter: Sangjin Lee
Assignee: Sangjin Lee
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).
