bharatviswa504 opened a new pull request #316: WIP:HDDS-2680. Fix updating lastAppliedIndex in OzoneManagerStateMachine. URL: https://github.com/apache/hadoop-ozone/pull/316 ## What changes were proposed in this pull request? This Jira is to fix a bug that has been caused by HDDS-2637. Now we have applyTransactionMap where we put all entries of ratisTransactionIndex before complete. And when updating lastAppliedIndex, now there is a chance that we updateLastAppliedIndex before DoubleBuffer flush has committed transactions to DB. Let's take 1-10 are apply transaction entries which are not flushed, 11th is indexUpdate a metadata/conf entry transaction, now when notifyIndexUpdate is called with 11, we updateLastAppliedIndex to 11. (Which we should not do) This Jira is to fix this issue. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-2680 ## How was this patch tested? Trying to add some UT's to test this.
