Description:
I found SlowDiskReport won't update when slowDisks is always empty in
org.apache.hadoop.hdfs.server.blockmanagement.*handleHeartbeat*, this may lead
to outdated SlowDiskReport alway staying in jmx of namenode until next time
slowDisks isn't empty. So i think this method
*checkAndUpdateReportIfNecessary()* should be called firstly when we want to
get the jmx information about SlowDiskReport, this can keep the SlowDiskReport
on jmx alway valid.

HaiBin Huang updated HDFS-14612:
Description:
I found SlowDiskReport won't update when slowDisks is always empty in
org.apache.hadoop.hdfs.server.blockmanagement.*handleHeartbeat*, this may lead
to outdated SlowDiskReport alway staying in jmx of namenode until next time
slowDisks isn't empty. So i think this method
*checkAndUpdateReportIfNecessary()* should be called firstly when we want to
get the jmx information about SlowDiskReport, instead of when we found some
slowdisk isn't empty ,this can keep the SlowDiskReport on jmx is alway valid.
There is also some incorrect object reference on
org.apache.hadoop.hdfs.server.datanode.fsdataset.
*DataNodeVolumeMetrics*
{code:java}
// Based on writeIoRate
public long getWriteIoSampleCount() {
return syncIoRate.lastStat().numSamples();
}
public double getWriteIoMean() {
return syncIoRate.lastStat().mean();
}
public double getWriteIoStdDev() {
return syncIoRate.lastStat().stddev();
}
{code}
