Yonik Seeley commented on SOLR-8561: ------------------------------------ Do we have any tests for rolling upgrades? Should we? > Add fallback to ZkController.getLeaderProps for a mixed 5.4-pre-5.4 > deployments > ------------------------------------------------------------------------------- > > Key: SOLR-8561 > URL: https://issues.apache.org/jira/browse/SOLR-8561 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Reporter: Shai Erera > Assignee: Shai Erera > Fix For: 5.5, 5.4.1 > > Attachments: SOLR-8561.patch, SOLR-8561.patch > > > See last comments in SOLR-7844. The latter changed the structure of the > leader path in ZK such that upgrading from pre-5.4 to 5.4 is impossible, > unless all nodes are taken down. This issue adds a fallback logic to look for > the leader properties on the old ZK node, as discussed. -- 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
