1、用kettle通過jdbc連接hiveserver2的時候拋出異常

Exception in thread "main" org.apache.hive.service.cli.HiveSQLException: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: hadoop is not allowed to impersonate anonymousat org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:258)at org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:249)at org.apache.hive.jdbc.HiveConnection.openSession(HiveConnection.java:579)at org.apache.hive.jdbc.HiveConnection.<init>(HiveConnection.java:167)at org.apache.hive.jdbc.HiveDriver.connect(HiveDriver.java:107)at java.sql.DriverManager.getConnection(DriverManager.java:571)at java.sql.DriverManager.getConnection(DriverManager.java:215)at client.main(client.java:21)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:606)at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140) Caused by: org.apache.hive.service.cli.HiveSQLException: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: hadoop is not allowed to impersonate anonymousat org.apache.hive.service.cli.session.SessionManager.openSession(SessionManager.java:324)at org.apache.hive.service.cli.CLIService.openSessionWithImpersonation(CLIService.java:187)at org.apache.hive.service.cli.thrift.ThriftCLIService.getSessionHandle(ThriftCLIService.java:424)at org.apache.hive.service.cli.thrift.ThriftCLIService.OpenSession(ThriftCLIService.java:318)at org.apache.hive.service.cli.thrift.TCLIService$Processor$OpenSession.getResult(TCLIService.java:1257)at org.apache.hive.service.cli.thrift.TCLIService$Processor$OpenSession.getResult(TCLIService.java:1242)at org.apache.thrift.ProcessFunction.process(ProcessFunction.java:39)at org.apache.thrift.TBaseProcessor.process(TBaseProcessor.java:39)at org.apache.hive.service.auth.TSetIpAddressProcessor.process(TSetIpAddressProcessor.java:56)at org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:286)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.RuntimeException: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: hadoop is not allowed to impersonate anonymousat org.apache.hive.service.cli.session.HiveSessionProxy.invoke(HiveSessionProxy.java:89)at org.apache.hive.service.cli.session.HiveSessionProxy.access$000(HiveSessionProxy.java:36)at org.apache.hive.service.cli.session.HiveSessionProxy$1.run(HiveSessionProxy.java:63)at java.security.AccessController.doPrivileged(Native Method)at javax.security.auth.Subject.doAs(Subject.java:422)at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657)at org.apache.hive.service.cli.session.HiveSessionProxy.invoke(HiveSessionProxy.java:59)at com.sun.proxy.$Proxy35.open(Unknown Source)at org.apache.hive.service.cli.session.SessionManager.openSession(SessionManager.java:315)... 12 more Caused by: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: hadoop is not allowed to impersonate anonymousat org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:554)at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:489)at org.apache.hive.service.cli.session.HiveSessionImpl.open(HiveSessionImpl.java:156)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

2、原因：hive不允許匿名用戶訪問

3、解決辦法：

在hdfs的core-site.xml文件添加兩個屬性

hadoop.proxyuser.hive.groups=* hadoop.proxyuser.hive.hosts=*

重啟hdfs、hive、yarn，MR
