Tsuyoshi OZAWA commented on HADOOP-11603:
-----------------------------------------
[~brahmareddy] the term "snapshot" is not related to HDFS snapshot in
MetricsSystemImpl:
{code}
/**
* Sample all the sources for a snapshot of metrics/tags
* @return the metrics buffer containing the snapshot
*/
synchronized MetricsBuffer sampleMetrics() {
{code}
Is it OK to close this as "Not a problem"?
> Snapshot log can be removed #MetricsSystemImpl.java since all the services
> will intialzed
