Sangjin Lee updated HADOOP-12747: --------------------------------- Attachment: HADOOP-12747.02.patch Posted patch v.2. Fixed the checkstyle issues. I believe the unit test failures are unrelated. I am unable to reproduce them locally, and other pre-commit runs seem to see them sporadically. > 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 > Attachments: HADOOP-12747.01.patch, HADOOP-12747.02.patch > > > 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
