## What changes were proposed in this pull request? HDDS-11558. HBase RegionServer crashes due to inconsistency caused by Ozone client failover handling Please describe your PR in detail: * Please see the jira for the reproduction steps. * This PR proposes to add a check before OM preExecute() step, such that if OM (inside its Hadoop RPC handler) receives a request that has been executed before, return its cached result. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-11558 ## How was this patch tested? The reproduction is complex. It involves pausing multiple OMs in specific lock steps. So I'm not able to write a test. It might be possible to write Docker-based acceptance test to simulate node pause though. I manually repeated the steps described in the jira several times to confirm the change fixed the problem. -- This is an automated message from the Apache Git Service.
