Subject [jira] [Commented] (HADOOP-15204) Add Configuration API for parsing storage sizes
Date Thu, 15 Feb 2018 17:24:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16365975#comment-16365975

Steve Loughran commented on HADOOP-15204:

bq. I plan to post an initial patch where I will convert the Ozone usage to getStorageUnits
and I will follow up with trunk later.

that'd be great! 
I suspect hadoop-* is the primary user of the getLongBytes call, so patching it in our code
will fix things.

Maybe consider tagging the method as Deprecated in the same patch, to warn other people

> 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.
