我正在设置 Apache Atlas，其中 Cassandra 作为后端，solr 作为索引器。以下是我对 Atlas-cassandra 的配置设置

   atlas.graph.storage.backend=cql
    atlas.graph.storage.hostname=cassandra-dc-service
    atlas.graph.storage.cassandra.keyspace=JanusGraph
    atlas.graph.storage.clustername=cstone-cassandra
    atlas.graph.storage.port=9042
  atlas.EntityAuditRepository.impl=org.apache.atlas.repository.audit.CassandraBasedAuditRepository
    atlas.EntityAuditRepository.keyspace=atlas_audit
    atlas.EntityAuditRepository.replicationFactor=1
    atlas.graph.storage.username=cassandra-superuser
    atlas.graph.storage.password=xxxxxx

我从（Apache atlas 2.1 configuration connection cassandra backend [help]）获得帮助来解决创建密钥空间的 cassandra 连接问题。但是 Atlas Service 没有提出以下例外：

我看到同样的开放 Jira 问题。如果有人已经解决了这个问题，请提出解决方法

在 Atlas 2.2.0 之前正式不支持经过身份验证的 Cassandra。但是在构建代码时，我们可以更新 PR 下面给出的两个文件并构建 Atlas。哪个按预期工作
