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

Thanks [~linyiqun]. I am +1 for the latest patch with a minor issue - the 
following line should also include the name of the configuration setting.
{code}
1660          throw new HadoopIllegalArgumentException("Loss of precision 
converting "
1661              + timeStr + vUnit.suffix() + " to " + unit);
{code}

I will hold off committing for now in case [~chris.douglas] or 
[~ste...@apache.org] have comments. Steve - I think the only open question was 
whether to add week/year suffixes. I don't have an opinion either way.

> HDFS configuration without time unit name should accept friendly time units

> 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.
