Yonger commented on HADOOP-14475:
---------------------------------
[[email protected]] I found the output of metrics missing part of metrics in
streamMetrics HashMap, because they didn't register into MetricsRegistry.
With my understand, i will remove streamMetrics HashMap, and register stream
related metrics directly like method "counter".
But i note there is function "dump" will read from this HashMap, and few other
class call this dump method to print stream metrics. I don't think it's a good
idea to print any metrics to log file, we should put all performance metrics
into other place(e.g. a separate file or database) .
Any suggestion?
