Glen Geng created HDDS-4130:
-------------------------------
Summary: remove the 1st edition RatisServer of SCM HA, which is
copied from OM HA
Key: HDDS-4130
URL: https://issues.apache.org/jira/browse/HDDS-4130
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: SCM
Reporter: Glen Geng
Assignee: Glen Geng
The disk layout per volume is as follows:
{code:java}
../hdds/VERSION
../hdds/<<scmUuid>>/current/<<containerDir>>/<<containerID>>/metadata
../hdds/<<scmUuid>>/current/<<containerDir>>/<<containerID>>/<<dataDir>>{code}
However, after SCM-HA is enabled, a typical SCM group will consists of 3 SCMs,
each of the SCMs has its own scmUuid, meanwhile share the same clusterID.
Since federation is not supported yet, only one cluster is supported now, this
Jira will change scmID to clusterID for container and volume at Datanode side.
The disk layout after the change will be as follows:
{code:java}
../hdds/VERSION
../hdds/<<clusterID>>/current/<<containerDir>>/<<containerID>>/metadata
../hdds/<<clusterID>>/current/<<containerDir>>/<<containerID>>/<<dataDir>>{code}
