Description

Namenode,DataNode,journalnode,ResourceManager, Nodemanager and historyservice etc... will initialize DefaultMetricsSystem hence following log will be logged for all the classes.. Since there is snapshot feature in HDFS ,it's better to change the following...

LOG.info("Scheduled snapshot period at "+ period +" second(s).");
