Question

我使用端口10000从我的SQL工具（即Squirrel SQL，Oracle SQL Developer）到HiveServer2（在远程服务器上运行）建立JDBC连接。

我能够成功运行一些查询。然后我做了一些其他事情（不在SQL工具中）1-2分钟，然后返回我的SQL工具并尝试运行查询，但是我收到此错误：org.apache.thrift.transport.TTransportException: java.net.SocketException: Software caused connection abort: socket write error

如果我现在断开连接并重新连接我的SQL工具，我可以再次运行查询。但有谁知道我应该改变什么HiveServer2设置以防止错误？我在hive-site.xml中假设了一些东西

从下面的hiveserver2日志中，可以看到从第30分钟到第31分钟的确切1分钟间隙发生断开连接。

环境：

Hive 2.1.1，hive.server2.transport.mode设置为二进制（示例JDBC字符串为jdbc：hive2：// remotehost：10000 / default）
Hadoop 2.8.3
使用MySQL的Metastore
Java 8

Answer 1

将AWS ELB的默认超时从1分钟更改为20分钟
将SimbaHive驱动程序与Squirrel一起使用（无超时），或将标准apache hive2驱动程序与IBM数据工作室一起使用（无超时）

hiveserver2 org.apache.thrift.transport.TTransportException在一小段不活动后运行第二个查询时出错
