> Key: HDDS-1262
> URL: https://issues.apache.org/jira/browse/HDDS-1262
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
>
> 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.
