我有一个简单的测试应用程序来设置与Hive（简单身份验证）的会话。
CliSessionState localSession = new CliSessionState(hiveConf)
localSession.setIsHiveServerQuery(true)
localSession.setCurrentDatabase("LOOM")
Driver driver = new Driver(hiveConf)
SessionState.start(localSession) ///////////////////////////// 1.
List data = new ArrayList()
CommandProcessorResponse response = driver.run("SHOW TABLES") // 2.
driver.getResults(data)
data.each {
println "${it}" // I skipped table list in log output
}
driver.close()
if (localSession != null) {
localSession.close() ///////////////////////////////// 3.
}
一切正常。我在数据库LOOM中有一个表列表。没有错误或什么的。但是，日志输出看起来很可疑。有很多行如：
org.apache.hadoop.security.UserGroupInformation - 无法通过java.io.IOException获取用户配置单元的组：找不到用户配置单元的组
它是否表示我的代码，配置单元设置或其他问题？我该怎么做才能摆脱这些消息？
以下是应用日志。评论为1.，2.，3.的行会生成相应的行块：

更新
日志是这个应用程序的STDOUT / STDERR我在intellij idea中本地启动了（在集群上安装hadoop / hive我用* -site.xml＆＃39; s连接）
我实际上在服务器上的组hive中有一个本地用户hadoop。
我在intellij idea中设置IOException的断点并打开stacktrace的输出。以下是我的特定异常实例的堆栈跟踪：
