Change subject: KUDU-3437 Set default block_cache_metrics_policy to reset ...................................................................... Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/19585/3//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/19585/3//COMMIT_MSG@9 PS3, Line 9: empty local directories > You are correct, A,B,C are not restarted. You can see the exact commands in Ok, My advice is don't change the default value. I am afraid that it may cause some other problems. You can change the opt at add 'opts.set_block_cache_metrics_policy(Cache::ExistingMetricsPolicy::kReset);' before the second new Master' opt. like this: master_runner.cc: ` RETURN_NOT_OK(ClearLocalSystemCatalogAndCopy(leader_hp)); opts.set_block_cache_metrics_policy(Cache::ExistingMetricsPolicy::kReset); server.reset(new Master(opts)); ` By the way, currently, kudu-masters have no way 'membership change automatically'. If D can start normally, then you should also op A B C add D to their cmeta file and restart it to load their raft group membership. The process need an administrator. The administrator just like a coordinator do this. Of course, you can add this logic codes into kudu-masters. Add a member, remove a member, replace a exist member, some situations its useful, and at the same. time administrators always needed. -- To view, visit http://gerrit.cloudera.org:8080/19585 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Idc32d7ab02201382debcbe36311579550353bf71 Gerrit-Change-Number: 19585 Gerrit-PatchSet: 3 Gerrit-Owner: Ádám Bakai <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Attila Bukor <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Wang Xixu <[email protected]> Gerrit-Reviewer: Yuqi Du <[email protected]> Gerrit-Reviewer: Zoltan Chovan <[email protected]> Gerrit-Reviewer: Ádám Bakai <[email protected]> Gerrit-Comment-Date: Tue, 28 Mar 2023 04:28:12 +0000 Gerrit-HasComments: Yes
