1、用kettle通过jdbc连接hiveserver2的时候抛出异常
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)

3、解决办法：
在hdfs的core-site.xml文件添加两个属性
hadoop.proxyuser.hive.groups=*
hadoop.proxyuser.hive.hosts=*重启hdfs、hive、yarn，MR
