Question

我正在使用Cassandra作为后端和弹性搜索来部署Titan集群。

以下是不同部分的版本：

Titan DB    Cassandra   ES      Oracle-JDK   Ubuntu
0.4.4       1.2.X       0.90.3  1.7          14.04

我将此文章作为参考：http://datacommunitydc.org/blog/2013/12/setting-up-a-titan-cluster-on-cassandra-and-elasticsearch-on-aws-ec2/

我已经设置了两个集群，一个Cassandra集群和一个ES集群。

它们都已启动并运行，我已对它们进行了测试。

我的ES群集配置如下：

{
"cluster_name": "Elastic-Cluster",
"nodes": {
    "umUbyIWnTvWIXCzlitJZIg": {
        "hostname": "titan-cluster01",
        "http_address": "inet[/10.7.6.20:9200]",
        "name": "Elastic Node01",
        "transport_address": "inet[/10.7.6.20:9300]",
        "version": "0.90.13"
    },
    "xY1p4T4-R76gJU8R8DGXSA": {
        "hostname": "titan-cluster02",
        "http_address": "inet[/10.7.6.22:9200]",
        "name": "Elastic Node02",
        "transport_address": "inet[/10.7.6.22:9300]",
        "version": "0.90.13"
    }
},
"ok": true
}

我的文件titan-cassandra-es.properties的内容是：

storage.backend=cassandra
storage.hostname=10.7.6.20,10.7.6.22
storage.port=9160
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.25
storage.index.search.backend=elasticsearch
storage.index.search.hostname=10.7.6.20,10.7.6.22
storage.index.search.cluster-name="Elastic-Cluster"
storage.index.search.client-only=true

但是，当我尝试使用gremlin创建Titan实例时，我得到了同样的错误。似乎它不识别ES集群节点，因为它警告不存在的节点名称，节点为null。

gremlin>
gremlin> g = TitanFactory.open('/opt/titan/conf/titan-cassandra-es.properties')
WARN  org.elasticsearch.client.transport  - [Bishop] node null not part of the cluster Cluster ["Elastic-Cluster"], ignoring...
==>titangraph[cassandra:10.7.6.21]

提前致谢。

无法从Titan访问Elastic Search Cluster节点
