----------------------------------------
Summary: 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
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.
