Subject [jira] [Commented] (HDFS-4097) provide CLI support for create/delete/list snapshots
Date Tue, 23 Oct 2012 05:23:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13482123#comment-13482123

Suresh Srinivas commented on HDFS-4097:

The design document already covers admin operation for allowing snapshots and marking it as
snapshottable. Here are the Admin CLIs for that:
* Making a directory snapshottable: {{hadoop dfsadmin -allowSnapshot <path>}}
* Making a directory not snapshottable: {{hadoop dfsadmin -disallowSnapshot <path>}}

User/Admin CLIs for creating, deleting and listing snapshots:
* Creating a snapshot: {{hadoop dfs -createSnapshot <snapname> <path> <ro/rw>}}
* Deleting a snapshot: {{hadoop dfs –deleteSnapshot <snapname>}}
* Listing of the snapshots: {{hadoop dfs -listSnapshot}}

Will try to get an updated document posted by tomorrow with this information.
