java in.available_java.io.IOException: No error in nativeavailable
时间: 2024-06-05 09:12:56 浏览: 199
这个异常通常是由于调用`InputStream`的`available()`方法时,底层的系统调用返回了一个错误码。这个错误码可能是`EBADF`(文件描述符不正确)或`EINVAL`(参数无效)等。
可能的原因是你的程序在使用`InputStream`时,底层的文件描述符出现了问题,或者在调用`available()`方法时传入了无效的参数。
你可以尝试重新打开文件或者网络连接,或者检查你的代码是否正确地使用了`InputStream`。如果问题仍然存在,可以尝试在操作系统级别上排除故障。

java.io.IOException: SERVICE_NOT_AVAILABLE. Won’t retry the operation.给出解决办法
遇到`java.io.IOException: SERVICE_NOT_AVAILABLE`错误时,通常表示服务还未启动或者已停止运行,导致无法连接。这可能是由于以下几个原因:
1. **服务未启动**[^1]:
```java
// 检查GCM注册服务的状态
if (GoogleCloudMessaging.INSTANCE.isRegisteredOnServer()) {
// 如果服务器不可用,则不会自动重试
throw new IOException("SERVICE_NOT_AVAILABLE");
}
```
解决方案:确保GCM(Google Cloud Messaging)或类似服务已经正确配置并启动。
2. **HBase异常**[^2]:
```
ERROR: org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet
```
这表明HBase服务器尚未准备好接收请求。
解决方案:
- 检查HBase服务是否正在运行,可以通过命令行工具如`hadoop-daemon.sh status hbase-regionserver` 或 `hbase shell` 来查看。
- 确认HBase配置文件正确,并且服务已经按照HBase文档指南启动。
如果服务未运行,尝试手动启动它们;如果是配置问题,检查相关的启动脚本和配置设置。对于长期不稳定的状况,考虑增加重启策略或添加健康检查机制以避免频繁的失败操作。
java.io.IOException: Broken pipe
This error occurs when a program tries to write data to a closed or unreachable pipe/socket. In other words, the program is trying to send data to a destination that is no longer available or has been disconnected.
This error often occurs when a client program tries to communicate with a server program and the server program terminates unexpectedly or the connection between the client and server is lost. The client program may continue to send data to the server, but the server is no longer available to receive it, resulting in a broken pipe error.
To resolve this error, the program needs to handle the broken pipe exception and take appropriate action, such as closing the connection and notifying the user of the error. The program may also need to retry the operation or establish a new connection if possible.
