Ishan Chattopadhyaya commented on SOLR-13695: --------------------------------------------- Happened on 7.7.1. I don't have the logs now, but I can try to reproduce on master or 8.2 and attach logs. > SPLITSHARD (link), followed by DELETESHARD of parent shard causes data loss > --------------------------------------------------------------------------- > > Key: SOLR-13695 > URL: https://issues.apache.org/jira/browse/SOLR-13695 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Reporter: Ishan Chattopadhyaya > Assignee: Ishan Chattopadhyaya > Priority: Critical > > One of my clients experienced data loss with the following sequence of > operations: > 1) SPLITSHARD with method as "link". > 2) DELETESHARD of the parent (inactive) shard. > 3) Query for documents in the subshards, seems like both subshards have 0 > documents. > Proposing a fix (after offline discussion with [~noble.paul]) based on > running FORCEMERGE after SPLITSHARD (such that segments are rewritten), and > not letting DELETESHARD delete the data directory until the FORCEMERGE > operations finish. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
