Hello, In general, configuration property default values will be defined in two places: 1) hdfs-default.xml, which defines the default property values when a deployment doesn't specifically set them and 2) DFSConfigKeys, a class that defines constant default values that the code uses if for some reason no default value is found during the configuration lookup.
