Jitendra Nath Pandey updated HADOOP-13285:
------------------------------------------
Description:
HADOOP-13197 added non-decayed call metrics in metrics2 source for
DecayedRpcScheduler. However, CallVolumeSummary in MXBean was affected
unexpectedly to include both decayed and non-decayed call volume. The root
cause is Jackson ObjectMapper simply serialize all the content of the
callCounts map which contains both non-decayed and decayed counter after
HADOOP-13197. This ticket is opened to fix the CallVolumeSummary in MXBean to
include only decayed call volume for backward compatibility and add unit test
for DecayRpcScheduler MXBean to catch this in future.
