一、简介
运行gremlin console 连接hbase+elastricseach 测试操作titan，titan运行的环境是jdk1.8，Linux环境有安装了jdk1.8.0_11环境，符合titan所需的jdk1.8环境，运行./bin/gremlin.sh 报错了，运行不起来。
二、错误
[root@Master titan-1.0.0-hadoop2]# ./bin/gremlin.sh

三、分析
原先以为是titan的jar冲突了，排查了很久，看到了jdk1.8.0_11 的bug 只要升级最新的jdk版本1.8.0_121版本就可以正常运行起来。

gremlin> 接下来，开始对titan进行深入的了解，可以互相学习
