Erik Krogen commented on HDFS-14748:
------------------------------------
I don't see any reason this can't be configurable. Can you please fix the
checkstyle issues? I also think that the new {{minOutlierDetectionSamples}}
field should be {{final}} since it is only set in the constructor, and I think
that the new {{getMinOutlierDetectionSamples()}} method should be
package-private.
> Make DataNodePeerMetrics#minOutlierDetectionSamples configurable

> Slow node monitoring is to transfer 1000 packets between DataNodes within
> three hours before they are eligible to calculate and upload transmission
> delays to the namenode.
> But if Write data is very small and number of packets is less than 1000, the
> slow node will not be reported to NameNode, so make
> DataNodePeerMetrics#minOutlierDetectionSamplesconfigurable.
