Subject [jira] [Commented] (HDFS-5120) add command-line support for manipulating cache pools
Date Wed, 04 Sep 2013 03:23:53 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5120?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13757428#comment-13757428

Colin Patrick McCabe commented on HDFS-5120:

this patch just has cache pool command-line support.  We can add support for adding and removing
directives in HDFS-5158.

Creating / removing / modifying cache pools is a superuser-only operation.  This patch adds
commands to dfsadmin.

(In contrast, cache directives are NOT superuser only-- see HDFS-5158 for details.)
