Scott Blum commented on SOLR-8696: ---------------------------------- [~markrmil...@gmail.com] Yes, I get the breakpoint in OverseerCollectionMessageHandler#addReplica. I'm trying to follow up on [~shalinmangar]'s request to add a wait loop at the end of that method. But where I'm struggling is, I don't actually understand where and how the ZK cluster state ever gets updated in legacy mode. Who updates the ZK cluster state as a result of OverseerCollectionMessageHandler#addReplica? > Optimize overseer + startup > --------------------------- > > Key: SOLR-8696 > URL: https://issues.apache.org/jira/browse/SOLR-8696 > Project: Solr > Issue Type: Improvement > Components: SolrCloud > Affects Versions: 5.4.1 > Reporter: Scott Blum > Labels: patch, performance, solrcloud, startup > Attachments: SOLR-8696.patch > > > ZkController.publishAndWaitForDownStates() occurs before overseer election. > That means if there is currently no overseer, there is ironically no one to > actually service the down state changes it's waiting on. This particularly > affects a single-node cluster such as you might run locally for development. > Additionally, we're doing an unnecessary ZkStateReader forced refresh on all > Overseer operations. This isn't necessary because ZkStateReader keeps itself > up to date. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
