Retain Unified Archiving 4.11.0.1
 

Issue

After Updating to retain 4.11.0.1 configuring Solr8 Failed with Something went wrong, please check server logs for more information message and found the below line in RetainServer logs:

08:11:24, 902[ajp-apr-127.0.0.1-48009-exec-8] [ERROR] UpgradedEmbeddedSOLR: Failed to create or upload ZooKeeper configurations 
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /configs



Cause
From the ASConfig.cfg file there is some discrepancy with entries.
  1. The indexName is set to "localhost", while it should be "solr7"  (<indexName>localhost</indexName>)
  2. Under <zookeeperEnsemble> section, the zookeeperNamespacesolr7 entry is missing.
Resolution
Modifying the ASConfig.cfg file with the below changes:

1. The indexName is set to "localhost", it should be "solr7" 
<collectionName>xxxxxxxxxx</collectionName>
<indexName>localhost</indexName> to <indexName>solr7</indexName>

2.Under <zookeeperEnsemble> section, the zookeeperNamespacesolr7 entry is missing, i.e 
<zookeeperNamespace>solr7</zookeeperNamespace>

So, the entry should look like this: 
<zookeeperEnsemble>
<com.gwava.model.indexing.ZookeeperInfo>
<zookeeperPort>9081</zookeeperPort>
<zookeeperHost>localhost</zookeeperHost>
<zookeeperNamespace>solr7</zookeeperNamespace>
<embeddedSolr>true</embeddedSolr>
<isLocalJMXAddress>true</isLocalJMXAddress>
</com.gwava.model.indexing.ZookeeperInfo>
</zookeeperEnsemble>
