Bharat Viswanadham updated HDDS-1262:
-------------------------------------
Description:
In OM HA, currently, when openKey is called, in applyTransaction() on all OM
nodes, we make a call to SCM and write the allocateBlock information into OM DB
and also clientID will be generated by each OM node.
The proposed approach is:
1. In startTransaction, call openKey and the response returned should be used
to create a new OmRequest object and used in setting the transaction context.
And also modify the ozoneManager and KeymanagerImpl to handle the code with and
without ratis.
This Jira also implements HDDS-1319.
