Sean Busbey commented on HBASE-15737:
-------------------------------------
bq. Our codebase should be consistent w.r.t. the usage of stop watch.
I don't understand, why? We set a goal of removing it from hbase-client for a
very specific reason. The issue wasn't Stopwatch, it was that there were Guava
things at all.
What is the issue with making use of a class that's been present since Guava 10
and AFAICT is still present in the current Guava SNAPSHOT? Is the issue that
it's annotated Beta? Should we be removing Beta annotated Guava use entirely?

> HBASE-14963 removed reference to Guava Stopwatch from hbase-client module.
> However, there're still 3 classes referring to Guava Stopwatch :
> hbase-client/src/test/java/org/apache/hadoop/hbase/client/TestClientNoCluster.java:import
> com.google.common.base.Stopwatch;
> hbase-server/src/main/java/org/apache/hadoop/hbase/util/JvmPauseMonitor.java:import
> com.google.common.base.Stopwatch;
> hbase-server/src/test/java/org/apache/hadoop/hbase/ScanPerformanceEvaluation.java:import
> com.google.common.base.Stopwatch;
> We should remove reference to Guava Stopwatch.
> hadoop is no longer referencing Guava Stopwatch.
