Subject [jira] [Commented] (HDFS-5326) add modifyDirective to cacheAdmin
Date Fri, 18 Oct 2013 22:33:42 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13799606#comment-13799606
] 

Colin Patrick McCabe commented on HDFS-5326:
--------------------------------------------

I took a whack at this this morning.  I ended up reorganizing the types a little bit-- basically
creating a type for PBCDs where all the fields were optional (nullable), but continuing to
combine that with factories that did validation.  It's not quite ready to post but hopefully
I'll have it soon.

> We should add a way of modifying cache directives on the command-line, similar to how
modifyCachePool works.
