我使用的是JanusGraph Java API,HBase作为存储后端
我必须提到的一件事是我可以在JanusGraph shell中成功运行相同的命令, gremlin.sh
错误之前的日志如下,这在图形实例打开期间发生, JanusGraphFactory.open(jg.properties)

07:20:46.182 [main] WARN o.j.d.hbase.HBaseStoreManager - Unexpected exception during getDeployment()
而错误是

我不知道这个TemporaryBackendException,有没有人见过这个？
janusgraph配置的一部分是
gremlin.graph=org.janusgraph.core.JanusGraphFactory
cluster.max-partitions=64
storage.backend=hbase
storage.batch-loading=true
storage.hostname=cdh-master1,cdh-master2,cdh-master3
其中cdh-master1,2,3是动物园管理员仲裁,版本2.0 JanusGraph,HBase的1.2
完整的堆栈跟踪是
at my.graph.Graph.<clinit>(Graph.java:7) …我在MAC上使用PyCharm通过以下方式导入一些软件包
import pymongo
import bson
但是错误是 ModuleNotFoundError: No module named 'pymongo'
软件包已成功安装，并且在命令行中运行它们时没有任何问题，我还检查了Pycharm中的解释器配置，已将其固定为Python 3.6（我唯一的Python 3版本）
此外，当我使用pip3 freeze它表明这些软件包安装成功
我该如何解决这个问题？
