@ivandika3 , Since HddsClientUtils.containsException below will cover this case, let's remove catch (GroupMismatchException gme) {...}?

From the https://issues.apache.org/jira/browse/HDDS-10750?focusedCommentId=17847435&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17847435 in HDDS-10750, it's found
GroupMismatchExceptionare thrown during theClosePipelineCommandHandler.This is because
XceiverRatisServer#removeGroupis called beforeXceiverRatisServer#getRaftPeersInPipeline, which causesXceiverRatisServer#getRaftPeersInPipelineto throwGroupMismatchExceptionwhen it's trying to get theRaftServerProxy#getDivisionsince the group has been removed.Therefore, we need to first call the
XceiverRatisServer#getRaftPeersInPipelinebefore callingXceiverRatisServer#removeGroup.This patch also catch the
GroupMismatchExceptionin case the group has been removed by earlierClosePipelineCommandHandlerin other datanode for the same pipeline. The datanode will also try to remove the Ratis group from the other datanodes (ignoring the GroupMismatchException) before removing its own Ratis group.What is the link to the Apache JIRA
