亚马逊EMR上的TitanDB

Question

我正在尝试在Amazon EMR（2.4 + 0.94.18）上运行TitanDB（0.54）。当我试图与gremlin连接时，它会卡住。

``` ] $ bin / gremlin.sh

     \,,,/
     (o o)

----- OOOO - （_） - - - - - OOOO 的gremlin＆GT; g = TitanFactory.open（“hbase：localhost”） ```

如果我查看HBase日志，我可以看到发生了一些事情，直到我杀死了gremlin。日志正在填充：

这是第一次运行，我假设Titan正在尝试构建一个表但由于某种原因它不起作用。

解决方案是使用hbase而不是hbase-client版0.94.18重新编译Titan
