Subject [jira] [Updated] (HDFS-4230) Listing all the current snapshottable directories
Date Wed, 28 Nov 2012 01:36:58 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4230?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jing Zhao updated HDFS-4230:

    Attachment: HDFS-4230.001.patch

Initial patch uploaded. 

Unlike ClientProtocol#getListing and listCorruptFiles, this patch simply returns all the current
snapshottable directories, considering 1) the number of snapshottable directories may be not
very large, and 2) currently all the snapshottable directories are stored in an unsorted list
in the SnapshotManager thus it is hard to continue the listing from the middle.
