Scott Blum created SOLR-8697: -------------------------------- Summary: Fix LeaderElector issues Key: SOLR-8697 URL: https://issues.apache.org/jira/browse/SOLR-8697 Project: Solr Issue Type: Bug Components: SolrCloud Affects Versions: 5.4.1 Reporter: Scott Blum
This patch is still somewhat WIP for a couple of reasons: 1) Still debugging test failures. 2) This will more scrutiny from knowledgable folks! There are some subtle bugs with the current implementation of LeaderElector, best demonstrated by the following test: 1) Start up a small single-node solrcloud. it should be become Overseer. 2) kill -9 the solrcloud process and immediately start a new one. 3) The new process won't become overseer. The old process's ZK leader elect node has not yet disappeared, and the new process fails to set appropriate watches. NOTE: this is only reproducible if the new node is able to start up and join the election quickly. -- 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
