Subject [jira] [Updated] (HADOOP-11603) Metric Snapshot log can be changed #MetricsSystemImpl.java since all the services will be initialized
Date Tue, 26 Apr 2016 03:07:12 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11603?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brahma Reddy Battula updated HADOOP-11603:
------------------------------------------
    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...
{code}
LOG.info("Scheduled snapshot period at "+ period +" second(s).");
{code}

  was:
Namenode,DataNode,journalnode,ResourceManager, Nodemanager and historyservice etc... will
initialize DefaultMetricsSystem hence following log will be logged for all the classes which
is not correct.. since snapshot feature is related to HDFS and this can be logged when snapshot
is enabled.

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