Change subject: IMPALA-8460: Simplify cluster membership management ...................................................................... Patch Set 6: (1 comment) http://gerrit.cloudera.org:8080/#/c/13207/6/be/src/scheduling/cluster-membership-mgr.h File be/src/scheduling/cluster-membership-mgr.h: http://gerrit.cloudera.org:8080/#/c/13207/6/be/src/scheduling/cluster-membership-mgr.h@125 PS6, Line 125: void SetLocalBeDescFn(BackendDescriptorPtrFn fn); > Unfortunately I don't think these Set*Fn() functions are really thread-safe I ended up with the second approach. Deferring Init() of the ClusterMembershipMgr until the ImpalaServer registers itself with the ExecEnv also would have meant to defer the initialization of the Scheduler and AdmissionController and I found the additional synchronization easier to reason about than changing our initialization order and interlacing it with ImpalaServer::Start(). Let me know if you feel that that's what we should do. -- To view, visit http://gerrit.cloudera.org:8080/13207 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ib3cf9a8bb060d0c6e9ec8868b7b21ce01f8740a3 Gerrit-Change-Number: 13207 Gerrit-PatchSet: 6 Gerrit-Owner: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Michael Ho <k...@cloudera.com> Gerrit-Reviewer: Thomas Marshall <tmarsh...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Comment-Date: Wed, 08 May 2019 21:28:49 +0000 Gerrit-HasComments: Yes
