I use JDBC to connect to HiverServer2, but failed?? I add the following content to the Hadoop's core-site.xml: <property> <name>hadoop.proxyuser.root.hosts</name> <value>*</value> </property> <property> <name>hadoop.proxyuser.root.groups</name> <value>*</value> </property>
But get the following message all the same, how can I solved it? Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://192.168.96.130:10000: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: root is not allowed to impersonate root] with root cause java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException:User: root is not allowed to impersonate root at org.apache.hadoop.ipc.Client.getRpcResponse(Client.java:1511) ~[na:na] at org.apache.hadoop.ipc.Client.call(Client.java:1457) ~[na:na] at org.apache.hadoop.ipc.Client.call(Client.java:1367) ~[na:na] at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:228) ~[na:na] at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:116) ~[na:na] at com.sun.proxy.$Proxy29.getFileInfo(Unknown Source) ~[na:na] at org.apache.hadoop.hdfs.protocolPB.ClientNamenodeProtocolTranslatorPB.getFileInfo(ClientNamenodeProtocolTranslatorPB.java:900) ~[na:na] at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) ~[na:na] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:na] at java.lang.reflect.Method.invoke(Method.java:497) ~[na:na] at org.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:422) ~[na:na] at org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invokeMethod(RetryInvocationHandler.java:165) ~[na:na] at org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invoke(RetryInvocationHandler.java:157) ~[na:na]
