Summary: Add. a command to list all snapshots for a snaphottable
root with snap Ids
Key: HDFS-15488
URL: https://issues.apache.org/jira/browse/HDFS-15488
Project: Hadoop HDFS
Issue Type: Sub-task
Components: snapshots
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Currently, the way to list snapshots is do a ls on
<snapshotttableRootPath>/.snapshot directory. Since creation time is not
recorded , there is no way to actually figure out the chronological order of
snapshots. The idea here is to add a command to list snapshots for a
snapshottable directory along with snapshot Ids which grow monotonically as
snapshots are created in the system. With snapID, it will be helpful to figure
out the chronology of snapshots in the system.
