[jira] Commented: (HADOOP-6287) Support units for configuration knobs

    [ https://issues.apache.org/jira/browse/HADOOP-6287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12760145#action_12760145 ] 

eric baldeschwieler commented on HADOOP-6287:
---------------------------------------------

We could add range checking and target units too.

Target units would let us deal with variables in the system like mapred.job.memory.mb.
We could make the whole thing a lot more self documenting at the same time...

> We should add support for units in our Configuration system so that we can specify values to be *1GB* or *1MB* rather than forcing every component which consumes such values to be aware of these.
