[jira] [Created] (HDFS-15817) Rename snapshots while marking them
deleted
Shashikant Banerjee created HDFS-15817:
------------------------------------------
Summary: Rename snapshots while marking them deleted
Key: HDFS-15817
URL: https://issues.apache.org/jira/browse/HDFS-15817
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Shashikant Banerjee
With ordered snapshot feature turned on, a snapshot will be just marked as deleted but won't actually be deleted if its not the oldest one. Since, the snapshot is just marked deleted, creation of new snapshot having the same name as the one which was marked deleted will fail. In order to mitigate such problems, the idea here is to rename the snapshot getting marked as deleted by appending deletion timestamp along with snapshot id to it.
