我第一次尝试使用janusgraph。我设置了一个hbase和solr的本地会话，但是当我尝试运行hbase和solr独立示例时：

mvn exec:java -pl :example-hbase -Dexample.config="\${project.basedir}/conf/jgex-hbase-solr-http.properties"

我得到这个堆栈跟踪错误：

到目前为止，我一直在遵循https://github.com/janusgraph/janusgraph/tree/master/janusgraph-examples/example-hbase 以及https://hbase.apache.org/book.html 这是在centos 7上运行的。我很确定这与我的hbase配置或jgex-hbase-solr-http.properties有关。我不确定在哪里可以找到导致graphfactory以这种方式失败的原因，但是任何帮助都将不胜感激。
谢谢您！
