Siddharth Seth created YARN-5194:
------------------------------------
Summary: Avoid adding yarn-site to all Configuration instances
created by the JVM
Key: YARN-5194
URL: https://issues.apache.org/jira/browse/YARN-5194
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Siddharth Seth
{code}
static {
addDeprecatedKeys();
Configuration.addDefaultResource(YARN_DEFAULT_CONFIGURATION_FILE);
Configuration.addDefaultResource(YARN_SITE_CONFIGURATION_FILE);
}
{code}
This puts the contents of yarn-default and yarn-site into every configuration
instance created in the VM after YarnConfiguration has been initialized.
This should be changed to a local addResource for the specific
YarnConfiguration instance, instead of polluting every Configuration instance.
Incompatible change. Have set the target version to 3.x.
The same applies to HdfsConfiguration (hdfs-site.xml), and Configuration
(core-site.xml etc).
core-site may be worth including everywhere, however it would be better to
expect users to explicitly add the relevant resources.
