Subject [jira] [Commented] (HDFS-11775) Ozone: KSM : add createBucket
Date Sat, 13 May 2017 22:40:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16009528#comment-16009528

Nandakumar commented on HDFS-11775:
-----------------------------------

Initial patch uploaded.
Based on offline discussion with [~anu] and [~xyao], BucketList is not stored separately in
levelDB. Since we don't have any upper limit on number of buckets, the list can become enormous.
So it has been decided to use DBIterator to extract the bucketNames from bucketInfo to get
BucketList.

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