--------------------------------------
Summary: ArrayIndexOutOfBoundsException if solr is down
Key: RANGER-3290
URL: https://issues.apache.org/jira/browse/RANGER-3290
Project: Ranger
Issue Type: Improvement
Components: audit
Reporter: Andras Salamon
[SolrCollectionBootstrapper|https://github.com/apache/ranger/blob/master/embeddedwebserver/src/main/java/org/apache/ranger/server/tomcat/SolrCollectionBootstrapper.java]
uploads a config to solr and creates a collection.
If solr is down (there are no live servers) during the collection creation
phase, we got a meaningful error message (from catalina.out):
{noformat}May 19, 2021 4:37:44 PM
org.apache.ranger.server.tomcat.SolrCollectionBootstrapper getCollections
SEVERE: getCollections() operation failed :
org.apache.solr.client.solrj.SolrServerException: No live SolrServers available
to handle this request{noformat}
On the other hand, if solr is down during the config upload phase the error
message is not too useful:
{noformat}May 20, 2021 8:07:59 AM
org.apache.ranger.server.tomcat.SolrCollectionBootstrapper uploadConfiguration
SEVERE: Error while uploading configs :
java.lang.ArrayIndexOutOfBoundsException: 0{noformat}
