- E0803 00:32:08.828233 111997 GeneratedCodeHelper.cpp:116] received invalid message from client: No version identifier… old protocol client in strict mode?
报这个错误是因为使用了高版本的客户端调用还是啥？有啥解决方法？还有这个strict mode怎么关掉？图数据库直接挂掉了
你把客户端的版本号补充下
<nebula.version>1.1.0</nebula.version>
现在这边突然挂掉了不知道如何分析
报错是有不对的客户端尝试访问这它的 thrift 接口，有没有人用不匹配的客户端或者其他协议客户端比如 http(curl) 去访问了服务的 thrift 接口？（像这个 对metad进行迁移 - #7，来自 ThomasWang ）
按理说这个报错应该不会造成数据库 crash 的，也许这个报错不是根因，服务可以起来么？
重启后服务可以起来，如果发现crash了，如何定位crash原因？
或者需要哪些信息我这里也可以提供下
是哪些进程 crash 了？日志都看过了么？能排除 OOM 么(dmesg |grep nebula)？
还有一个就是在阿里云访问图数据库经常会有这个错误 com.facebook.thrift.transport.TTransportException: java.net.SocketException: Broken pipe (Write failed) 查询的代码是这样的
public List<Map<String, Object>> query(String nGql) {
List<Map<String, Object>> resultsList = new ArrayList<>();
try {
ResultSet resultSet = client.get().executeQuery(nGql);
// 没有查询到结果
List<ResultSet.Result> results = resultSet.getResults();
if (results == null || results.isEmpty()) {
return resultsList;
}
for (ResultSet.Result result : results) {
Map<String, Object> resultMap = new HashMap<>();
for (String column : resultSet.getColumns()) {
Object value = result.get(column).getFieldValue();
if (value instanceof byte[]) {
resultMap.put(column, result.getString(column));
} else {
resultMap.put(column, value);
}
}
resultsList.add(resultMap);
}
} catch (Exception e) {
logger.error("query exception. " + nGql + " " + e.toString(), e);
}
现在已经重启了，还能看得到这些信息？
之前crash的信息就在之前的log里，如果有，不过 OOM 的您能看下么？ dmesg | grep nebula
我输入了这个命令没有任何反应
dmesg 就是看操作系统的 d message，如果所有 server grep 出来都没有的话说明没有 nebula 字样的 message。
我看了下都没有
我这个是查询出现的，出现这个就会查询不到数据，抛异常，查询数据的时候需要我每次查询完后关闭连接？
