Subject [jira] [Commented] (HDFS-11775) Ozone: KSM : add createBucket
Date Wed, 17 May 2017 17:42:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16014481#comment-16014481

Xiaoyu Yao commented on HDFS-11775:
-----------------------------------

[~vagarychen], HDFS-11769 already has a $ prefix for USERNAME entries to differentiate. Thanks
[~msingh] for mentioning this offline.
So I think we should be fine even without a / as prefix for volume if we check and ensure
that volume name should never start with $. 
Given we are adding a common prefix "/" for volume/bucket/key, the user entries won't collide
with them.

> Creates a bucket if it does not exist. A precondition to creating a bucket is that a
parent volume must exist.
