-----------------------------------------
Summary: Make unjar in RunJar overrideable
Key: HADOOP-15477
URL: https://issues.apache.org/jira/browse/HADOOP-15477
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 3.0.2, 2.7.6, 2.9.1, 2.8.3
Reporter: Johan Gustavsson
Currently Hadoop's RunJar will unjar the jar provided and look for any jars
inside and add them to the classpath. Since most deployments doesn't use jar in
jar, but rather uberjars this could be rather time consuming at times and can
cause issues related to over consumption of inodes, for something that is in
many cases is not used.
For that purpose there should be an env variable to disable this behavior.
