Summary: Ozone: KSM : add listVolumes
Key: HDFS-11773
URL: https://issues.apache.org/jira/browse/HDFS-11773
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Anu Engineer
List volume call can be used in three different contexts. One is for the
administrators to list all volumes in a cluster. Second is for the
administrator to list the volumes owned by a specific user. Third is a user
listing the volumes owned by himself/herself.
Since these calls can return large number of entries the rest protocol supports
paging. Paging is supported by the use of prevKey, prefix and maxKeys. The
caller is aware the this call is neither atomic nor consistent. So we can
iterate over the list even while changes are happening to the list.
