Summary: [Ozone upgrade] Support Upgrading HDFS clusters to use
Ozone
Key: HDDS-1266
URL: https://issues.apache.org/jira/browse/HDDS-1266
Project: Hadoop Distributed Data Store
Issue Type: New Feature
Reporter: Anu Engineer
Assignee: Anu Engineer
This is the master JIRA to support upgrading existing HDFS clusters to have
Ozone running concurrently. One of the requirements is that we support
upgrading from HDFS to Ozone, without a full data copy. This requirement is
called "In Place upgrade", the end result of such an upgrade would be to have
the HDFS data appear in Ozone as if Ozone has taken a snap-shot of the HDFS
data. Once upgrade is complete, Ozone and HDFS will act as independent systems.
I will post a design document soon.
