hdfs du periodicity and hdfs not respond at that time
hi all,
I found hdfs du periodicity(one hour), and because my disk is big, the
smallest one is 15T, so when hdfs exec du, datanode will not respond for
about 3 minuts because of io loading, this cause a lot of problem, anybody
knows why hdfs doing this and how to disable it?

Thanks &  Regards
