Michael Moss commented on HADOOP-12360:
---------------------------------------
Hi, I'm curious what this section of code is trying to achieve:
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/metrics2/sink/StatsDSink.java#L103
It seems that in some cases, for some metrics (JVM metrics for example), the sn
(serviceName) variable is overridden, which breaks the configured prefix:
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/metrics2/sink/StatsDSink.java#L91
Wondering if this was intended?
