Subject [jira] [Commented] (HADOOP-11603) Snapshot log can be removed #MetricsSystemImpl.java since all the services will intialzed
Date Mon, 16 Feb 2015 15:03:11 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11603?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14322834#comment-14322834

Tsuyoshi OZAWA commented on HADOOP-11603:

[~brahmareddy] the term "snapshot" is not related to HDFS snapshot in MetricsSystemImpl:

   * Sample all the sources for a snapshot of metrics/tags
   * @return  the metrics buffer containing the snapshot
  synchronized MetricsBuffer sampleMetrics() {

Is it OK to close this as "Not a problem"?

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}
