Steve Loughran commented on HADOOP-15204:
-----------------------------------------
catching up on this.
I'm disappointed by the lack of switching getLongBytes to use this behind the
scenes, as now, unless all uses of that method across the hadoop libraries are
changed to this new method, you are going to be able to specify sizes in some
configs which aren't valid in others, which means that we are exposing
historical implementation details to people configuring files.
Given its in, I'd like to see a followup "move existing uses of getLongBytes to
getStorageUnits"
> Add Configuration API for parsing storage sizes

> Hadoop has a lot of configurations that specify memory and disk size. This
> JIRA proposes to add an API like {{Configuration.getStorageSize}} which will
> allow users
> to specify units like KB, MB, GB etc. This is JIRA is inspired by
> HADOOP-8608 and Ozone. Adding {{getTimeDuration}} support was a great
> improvement for ozone code base, this JIRA hopes to do the same thing for
> configs that deal with disk and memory usage.
