    • Release Note:
      It is now possible to specify multiple jar files for the libjars argument using a wildcard. For example, you can specify "-libjars 'libs/*'" as a shorthand for all jars in the libs directory.

      Description

      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).
