ASF subversion and git services commented on SOLR-6086: ------------------------------------------------------- Commit 90da5ce81cea82424dad6ba9ab1bf12d34d196e2 in lucene-solr's branch refs/heads/master from [~shalinmangar] [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=90da5ce ] SOLR-6086: Replica is active during autowarming resulting in queries being sent to a replica that may not have a registered searcher. This causes spikes in response times when adding a replica in busy clusters > Replica active during Warming > ----------------------------- > > Key: SOLR-6086 > URL: https://issues.apache.org/jira/browse/SOLR-6086 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Affects Versions: 4.6.1, 4.8.1 > Reporter: Ludovic Boutros > Assignee: Shalin Shekhar Mangar > Labels: difficulty-medium, impact-medium > Attachments: SOLR-6086.patch, SOLR-6086.patch, SOLR-6086.patch, > SOLR-6086.patch, SOLR-6086-temp.patch > > Original Estimate: 72h > Remaining Estimate: 72h > > At least with Solr 4.6.1, replica are considered as active during the warming > process. > This means that if you restart a replica or create a new one, queries will > be send to this replica and the query will hang until the end of the warming > process (If cold searchers are not used). > You cannot add or restart a node silently anymore. > I think that the fact that the replica is active is not a bad thing. > But, the HttpShardHandler and the CloudSolrServer class should take the > warming process in account. > Currently, I have developped a new very simple component which check that a > searcher is registered. > I am also developping custom HttpShardHandler and CloudSolrServer classes > which will check the warming process in addition to the ACTIVE status in the > cluster state. > This seems to be more a workaround than a solution but that's all I can do in > this version. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
