As an AI language model, I cannot access the internal working of org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback and org.apache.hadoop.security.GroupMappingServiceProvider. However, I can tell you that both are classes in the Hadoop security package, and JniBasedUnixGroupsMappingWithFallback is a subclass of GroupMappingServiceProvider. The former is used as a fallback mechanism for the latter when the latter fails to retrieve group information from the operating system. JniBasedUnixGroupsMappingWithFallback uses JNI (Java Native Interface) to call native Unix functions to retrieve group information.
