[jira] [Created] (HDDS-4684) Use applyTransactionSerial instead of applyTransaction

Rui Wang created HDDS-4684:
------------------------------

             Summary: Use applyTransactionSerial instead of applyTransaction
                 Key: HDDS-4684
                 URL: https://issues.apache.org/jira/browse/HDDS-4684
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Rui Wang
            Assignee: Rui Wang


applyTransactionSerial is expected to execute transaction serializable while applyTransaction potentially run transaction in parallel. 

However, in current SCM state machine, applyTransaction waits each operation to finish even it returns CompleteFuture. So we should use applyTransactionSerial and leave applyTransaction returns null.
