---------------------------------
> Convert all MPU related operations to HA model
> ----------------------------------------------
>
> Key: HDDS-1440
> URL: https://issues.apache.org/jira/browse/HDDS-1440
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
> Fix For: 0.5.0
>
>
> In this jira, we shall convert all OM related operations to OM HA model,
> which is a 2 step.
> # StartTransaction, where we validate request and check for any errors and
> return the response.
> # ApplyTransaction, where original OM request will have a response which
> needs to be applied to OM DB. This step is just to apply response to Om DB.
> In this way, all requests which are failed with like volume not found or some
> conditions which i have not satisfied like when deleting volume should be
> empty, these all will be executed during startTransaction, and if it fails
> these requests will not be written to raft log also.
