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.
