New Contributor

my hadoop cluster is use ambari HDP-2.6.5.0 install and deploy.

i look up the hdfs -> metrics -> WriteBlockAvgTime value is very high.The max value is 2156796ms, avg value 121299.856ms and min value 285.96ms.

ReadBlockAvgTime value is very high.The max value is 38794.011ms, avg value 1678.979ms and min value 3.821ms.

and, try to optimize config for hadoop-du:

fs.getspaceused.jitterMillis=3600000

fs.du.interval=86400000

dfs.datanode.cached-dfsused.check.interval.ms=14400000

bu, no obvious effect.
