janusgraph无法使用configuredgraphfactory()和hbase作为存储后端创建和打开图形

我使用janusgraph创建多个图形并存储在hbase中。其目的是为不同的项目提供不同的图形集。project1有[proj1\u graph1。。。项目1\u graphn]和项目2有[proj2\u graph1…proj2\u graphm]。
参考（a）janusgraph手册，（b）问题1（c）示例1（d）示例2中的步骤，我尝试了以下步骤。但是，janusgraph似乎无法在hbase中创建图形。尽管在hbase中看到了该表，但该表已损坏。因此，当我试图打开图形时，janusgraph超时并返回error。
以下是重新生成的步骤：
在服务器端
（a） 定义gremlin-server-configuredgraph.yaml

host: 127.0.0.1
port: 8182
scriptEvaluationTimeout: 30000
channelizer: org.janusgraph.channelizers.JanusGraphWebSocketChannelizer

           org.apache.tinkerpop.gremlin.tinkergraph.jsr223.TinkerGraphGremlinPlugin: {},
           org.apache.tinkerpop.gremlin.jsr223.ImportGremlinPlugin: {classImports: [java.lang.Math], methodImports: [java.lang.Math#*]},
           org.apache.tinkerpop.gremlin.jsr223.ScriptFileGremlinPlugin: {files: []}}}}
serializers:
  - { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0, config: { ioRegistries: [org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry] }}

processors:
  - { className: org.apache.tinkerpop.gremlin.server.op.session.SessionOpProcessor, config: { sessionTimeout: 28800000 }}
  - { className: org.apache.tinkerpop.gremlin.server.op.traversal.TraversalOpProcessor, config: { cacheExpirationTime: 600000, cacheMaxSize: 1000 }}

maxAccumulationBufferComponents: 1024
resultIterationBatchSize: 64
writeBufferLowWaterMark: 32768
writeBufferHighWaterMark: 65536

（b） 定义janusgraph-hbase-confuglationgraph.properties

gremlin.graph=org.janusgraph.core.ConfiguredGraphFactory
storage.backend=hbase
graph.graphname=ConfigurationManagementGraph
storage.hostname=127.0.0.1
cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5

（c） 跑

bin/gremlin-server.sh conf/gremlin-server/gremlin-server-configuredgraph.yaml

在客户端，我运行以下命令并发现一个超时错误

gremlin> :remote connect tinkerpop.server conf/remote-uui.yaml session

我可以知道我是否做错了什么，或者这个功能还没有用hbase进行彻底的测试吗？我是否可以遵循其他步骤来实现我的目标，即使用不同的键空间创建多个图形

我认为要在一开始创建一个图，您必须使用janusgraphfactory，这将创建一个新的键空间，然后要绑定其他示例janusgraph，请在janusgraph.properties文件中使用graph.replace-instance-if-exists=true。最后，要创建多个图形，请在gremlin-server.yaml中添加其他conf文件的路径：

graphs: {
  graph: /janusgraph-config/janusgraph.properties
  graph2: /janusgraph-config/janusgraph2.properties
}
