[jira] [Created] (HDDS-10019) Simplify updateLastAppliedIndex in OzoneManagerStateMachine

Tsz-wo Sze created HDDS-10019:
---------------------------------

             Summary: Simplify updateLastAppliedIndex in OzoneManagerStateMachine
                 Key: HDDS-10019
                 URL: https://issues.apache.org/jira/browse/HDDS-10019
             Project: Apache Ozone
          Issue Type: Improvement
          Components: OM HA
            Reporter: Tsz-wo Sze


HDDS-2680 added some complicated logic to updateLastAppliedIndex.  It leads to some bugs like HDDS-9342.

This JIRA is to investigate some ways to simplify the logic.  In particular, we should remove data structure / interface like
- OzoneManagerStateMachine
-* applyTransactionMap
-* ratisTransactionMap
- OzoneManagerDoubleBuffer
-* indexToTerm (HDDS-10006)
-* ozoneManagerRatisSnapShot
-* currentFutureQueue
-* readyFutureQueue
