[jira] Commented: (HADOOP-6655) SLA related changes in hadoop-policy.xml have misleading property descriptions

["Vinod K V (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-6655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12848756#action_12848756 ] 

Vinod K V commented on HADOOP-6655:
-----------------------------------

Kos, the ACL proposed in HADOOP-4348 actually used a space character as the user-group list separator. The same AccessControlList is used for other features like queue administration and I know of code throughout MapReduce that hardcodes this same assumption for the lack of good API to deconstruct an ACL or modify an already constructed ACL.

Are you proposing we change the character separator to a semi-coloon? Any reason for this? Now?

> In the patch introduced my HADOOP-4348 proposed modifications of {{hadoop-policy.xml}} read on more than one occasion:

> +    The ACL is a comma-separated list of user and group names. The user and

> {noformat}
> It is either should read "separated by a semicolon" or the given example has to be changed.
