bharatviswa504 opened a new pull request #609: HDDS-3069. UpdateID check should be skipped for non-HA OzoneManager. URL: https://github.com/apache/hadoop-ozone/pull/609 ## What changes were proposed in this pull request? Donot have precondition check of updateID in non-HA OM cluster. // Because in non-HA, we have multiple rpc handler threads and // transactionID is generated in OzoneManagerServerSideTranslatorPB. // Lets take T1 -> Set Bucket Property // T2 -> Set Bucket Acl // Now T2 got lock first, so updateID will be set to 2. Now when T1 gets // executed we will hit the precondition exception. So for OM non-HA with // out ratis we should not have this check. // Same can happen after OM restart also. // OM Start // T1 -> Create Bucket // T2 -> Set Bucket Property // OM restart // T1 -> Set Bucket Acl // So when T1 is executing, Bucket will have updateID 2 which is set by T2 // execution before restart. // Main reason, in non-HA transaction Index after restart starts from 0. // And also because of this same reason we don't do replay checks in non-HA. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-3069 ## How was this patch tested?
