----------------------------------------

             Summary: In OM HA AllocateBlock call from OM should not happen on Ratis
                 Key: HDDS-1250
                 URL: https://issues.apache.org/jira/browse/HDDS-1250
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Bharat Viswanadham
            Assignee: Bharat Viswanadham


In OM HA, currently when allocateBlock is called, in applyTransaction() on all OM nodes,
we make a call to SCM and write the allocateBlock information into OM DB. The problem with
this is, every OM allocateBlock and appends new BlockInfo into OMKeyInfom and also this a
correctness issue. (As all OM's should have the same block information for a key, even though
eventually this might be changed during key commit)
