public class CoreDefaultProperties
extends java.util.Properties

Background: This class came into existence as part of HDFS unification effort (i.e. creation of a hadoop-common that both MR1 and MR2 can depend on) The "hadoop-common" in this context is the "hadoop-common" project from hadoop2 code base in git.(https://github.com/mapr/private-hadoop-common/tree/ branch-2.3-mapr/hadoop-common-project/hadoop-common) The idea behind this class is as follows: - The modifications to "hadoop-common" project should be generic, as MapR wants to submit the changes back to apache community in the future. - So, MapRConf cannot really live in hadoop-common. Hence it has been moved into maprfs jar under the name CoreDefaultProperties. - org.apache.hadoop.conf.Configuration in "hadoop-common" has been modified to support loading default configuration from a class named "org.apache.hadoop.conf.CoreDefaultProperties" that extends j.u.Properties. - Configuration first loads the properties from core-default.xml. - If CoreDefaultProperties exists in the classpath, then Configuration would load the configuration from this class before loading the configuration from core-site.xml. - Thus MapR version of CoreDefaultProperties would be equivalent to core-default.xml. Objective for this class: - Define the MapR specific default FS configuration (core-default.xml) in one place and make it available for both MR1 and MR2. Author: smarella
