Nathan Neulinger created SOLR-5638: -------------------------------------- Summary: Collection creation partially works, but results in unusable configuration due to missing config in ZK Key: SOLR-5638 URL: https://issues.apache.org/jira/browse/SOLR-5638 Project: Solr Issue Type: Bug Components: SolrCloud Affects Versions: 4.6 Reporter: Nathan Neulinger
Need help properly recovering from 'collection gets created without config being defined'. Right now, if you submit a collection create and the config is missing, it will proceed with partially creating cores, but then the cores fail to load. This requires manual intervention on the server to fix unless you pick a new colllection name: What's worse - if you retry the create a second time, it will usually try to create the replicas in the opposite order, resulting in TWO broken cores on each box, one for each attempted replica. beta1-newarch_hive1_v12_shard1_replica1: org.apache.solr.common.cloud.ZooKeeperException:org.apache.solr.common.cloud.ZooKeeperException: Specified config does not exist in ZooKeeper:hivepoint-unknown beta1-newarch_hive1_v12_shard1_replica2: org.apache.solr.common.cloud.ZooKeeperException:org.apache.solr.common.cloud.ZooKeeperException: Specified config does not exist in ZooKeeper:hivepoint-unknown I already know how to clear this up manually, but this is something where solr is allowing a condition in external service to result in a corrupted/partial configuration. I can see an easy option for resolving this as a workaround - allow a collection CREATE operation to specify "reuseCores" - i.e. allow it to use an existing core of the proper name if it already exists. Right now you wind up getting: org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'beta1-newarch_hive1_v12_shard1_replica1': Could not create a new core in solr/beta1-newarch_hive1_v12_shard1_replica1/as another core is already defined there org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'beta1-newarch_hive1_v12_shard1_replica2': Could not create a new core in solr/beta1-newarch_hive1_v12_shard1_replica2/as another core is already defined there -- This message was sent by Atlassian JIRA (v6.1.5#6160) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
