Hi All, I'm new to Hadoop and HDFS, currently, I'm reading source code and do some experimentation and I would like to contribute to the project. As I reading the source code I understood there are several cases of instantiation of Configuration class without any special parameters, for instance:
org.apache.hadoop.fs.DU line 98 org.apache.hadoop.metrics2.source.JvmMetrics line 120 org.apache.hadoop.io.WritableComparator line 128 org.apache.hadoop.conf.ReconfigurationServlet line 90 Do you think it's a good idea to keep a singleton instance of it as a static field for the usage which doesn't intend to change it (because it's a mutable class and some of these client class may change their instance)
