Subject [jira] [Commented] (HDFS-9847) HDFS configuration without time unit name should accept friendly time units

Arpit Agarwal commented on HDFS-9847:
-------------------------------------

Sorry I didn't understand your proposal to handle compatibility in the last para, agreed with
everything before that. To continue the example of heartbeat interval do you mean we continue
to query it with a unit of seconds for now and discard precision without throwing?

> 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.
