設置Titan和Cassandra - 無法實例化存儲管理器類

我設置了cassandra服務器（Datastax社區版）並且運行良好。設置Titan和Cassandra - 無法實例化存儲管理器類

我cassandra.yaml具有以下設置：

seeds: "127.0.0.1" 
storage_port: 7000 
rpc_port: 9160

當我這樣做是精怪殼：

conf = new BaseConfiguration(); 
conf.setProperty("storage.backend","cassandra"); 
conf.setProperty("storage.hostname","127.0.0.1"); 
conf.setProperty("storage.port",9160);

，並

g= TitanFactory.open(conf);

我得到這個錯誤：

你見過https://groups.google.com/forum/#!searchin/aureliusgraphs/Could$20not$20實例化$ 20storage $ 20manager $ 20class％7Csort：相關性/ aureliusgraphs/V-sMX6SMhe4/tz6lMRMWozkJ one ??? – abhi 2013-05-07 19:29:18

1）確保你在cassandra的同一臺機器上運行gremlin，否則你需要調整主機，如果這沒有幫助2）嘗試使用「casssandrathrift」作爲storage.backend – 2013-05-08 17:54:44

我面臨同樣的問題。解決方案是兼容版本檢查。我下載了最新版本的cassandra，錯誤消失了。

Apache的卡桑德拉 - 1.2.5

泰坦全0.3.1
