@1315861791 请问hugegraph是哪个版本？这个问题是超时了，可能数据量比较大。
fgz00 commentedon Dec 25, 2018
@javeme 您好，我用的版本是0.8.0，数据量在1万以内。我在配置文件中设置了超时时间也没用的。
配置如下：
task.wait_timeout=300
scriptEvaluationTimeout: 300000
我是在java 程序用用这行代码操作的：
hugeClient.graphs().clear(graphName,"I'm sure to delete all data");
javeme commentedon Dec 25, 2018
@1315861791 client也需要设置超时时间：
HugeClient(String url, String graph, int timeout)，另外请问使用的后端存储是什么类型？fgz00 commentedon Dec 25, 2018
@javeme 非常感谢。后端存储用的是hbase。
我给client设置了超时时间以后报错如下：

@javeme 多执行了几次就删除掉了。麻烦问一下我要做一个web服务的话client能不能像数据库连接池一样一直存在。如果我这样写的话会不会出现client过时的情况二无法使用：
private static HugeClient hugeClient;
javeme commentedon Dec 25, 2018
@1315861791 client可以一直存在的。
fgz00 commentedon Dec 25, 2018
@javeme 感谢你的回答，我是不是可以这样理解：HugeClient(String url, String graph, int timeout)，这里的timeout表示的是client提交的单个任务的超时时间？
javeme commentedon Dec 25, 2018
@1315861791 是的，具体是指一次发送request出去之后到接收到对应response之间的时间。
fgz00 commentedon Dec 25, 2018
@javeme 明白了，非常感谢！
