无法通过hbase客户端从titan连接到google bigtable

我正在尝试使用Hadoop2（hbase 1.0.2客户端）连接到titan 1.0.0（在中提供）https://github.com/thinkaurelius/titan/wiki/downloads)使用google云bigtable服务，使用其hbase客户端。
通过以下步骤，我可以成功地从gce示例中的hbase shell连接到bigtable。这个 hbase-site.xml 是根据模板，我已经下载了 ALPN_VERSION=8.1.5.v20150921 （oracle jdk se 1.8.0\u 60）

<configuration>
  <property>
    <name>hbase.client.connection.impl</name>
    <value>com.google.cloud.bigtable.hbase1_0.BigtableConnection</value>
  </property>
  <property>
    <name>google.bigtable.cluster.name</name>
    <value>[YOUR-CLUSTER-ID]</value>
  </property>
  <property>
    <name>google.bigtable.project.id</name>
    <value>[YOUR-PROJECT-ID]</value>
  </property>
  <property>
    <name>google.bigtable.zone.name</name>
    <value>[YOUR-ZONE-NAME]</value>
  </property>
</configuration>

然后，我抄了 hbase-site.xml 至 titan-1.0.0-hadoop2/conf 目录和bigtable jar到 titan-1.0.0-hadoop2/lib 文件夹。
然后，继续 titan-1.0.0-hadoop2 文件夹，我运行 ./run/gremlin.sh 启动控制台。
因此，当尝试使用hbase客户端（配置为指向bigtable群集）创建连接时。。。

TitanGraph graph = TitanFactory.build().set("storage.backend", "hbase").open();

…我在gremlin控制台中遇到以下异常：

com.google.cloud.bigtable.hbase1_0.BigtableConnection cannot be cast to org.apache.hadoop.hbase.client.ClusterConnection

以下是堆栈跟踪：

gremlin> TitanFactory.build().set("storage.backend", "hbase").open();

我发现了另一个问题，在其他上下文中也有同样的例外：无法使用hbase restapi连接到googlebigtable。
这个补丁能解决我和泰坦之间的这个例外吗？

泰坦不再维持；但是，您可以将janusgraph（泰坦的一个分支）与googlecloudbigtable一起使用；有关详细信息，请参阅以下指南：
在gcp上使用cloud bigtable运行janusgraph
配置janusgraph以连接到cloud bigtable
github托管janusgraph发行版。
