Problems: 1) Exception handling of delete is very different at 4 places ( on normal response, required failure, quorum failure) and after pipeline is finished. 2) The exceptions are reported again and again ( They are not removed from the map). 3) Some places ignore obsoleteVersionException, some others report it. 4) There is a zombie state abort, there is no way to reach this state. 5) Multiple slops could be sent, because of the issue 2. When the pipeline is aborted, no slops could be sent. 6) Refactored QuotaLimitingStore test to add delete test cases 7) Combined the PUT and GET quotas into 2 quotas. Solution: Defined a common method, so that all 4 places call into the same method. Only the condition for calling is different. Race conditions still exist, after zone failure check but before pipeline finishes the exception will go missing, slops will not happen, but the chances are reduced. Got rid of the state PerformDeletedHintHandoff as QuotaExceededExceptions will not be reported as failures. Now doing it in place.
