Chris Douglas commented on HDFS-9847:
-------------------------------------

Yeah, I agree it's not clear-cut. Attached a patch that includes units for all the vars changed
to TimeUnit in {{hdfs-default.xml}}, so it's clearer that this patch changed their type (compatibly)
in this release.

> In HDFS-9821, it talks about the issue of leting existing keys use friendly units e.g.
60s, 5m, 1d, 6w etc. But there are som configuration key names contain time unit name, like
{{dfs.blockreport.intervalMsec}}, so we can make some other configurations which without time
unit name to accept friendly time units. The time unit  {{seconds}} is frequently used in
hdfs. We can updating this configurations first.
