HiveSQLException: Error while compiling statement: No privilege 'Create' found for outputs { databas

今天用Hive的JDBC實例時出現了HiveSQLException: Error while compiling statement: No privilege 'Create' found for outputs { database:default }的錯誤，日誌以下。

org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: No privilege 'Create' found for outputs { database:default }  at org.apache.hive.jdbc.Utils.verifySuccess(Utils.java:231) at org.apache.hive.jdbc.Utils.verifySuccessWithInfo(Utils.java:217) at org.apache.hive.jdbc.HiveStatement.execute(HiveStatement.java:254) at zimo.hadoop.hive.Hive.main(Hive.java:27) Caused by: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: No privilege 'Create' found for outputs { database:default }  at org.apache.hive.service.cli.operation.Operation.toSQLException(Operation.java:314) at org.apache.hive.service.cli.operation.SQLOperation.prepare(SQLOperation.java:102) at org.apache.hive.service.cli.operation.SQLOperation.runInternal(SQLOperation.java:171) at org.apache.hive.service.cli.operation.Operation.run(Operation.java:256) at org.apache.hive.service.cli.session.HiveSessionImpl.executeStatementInternal(HiveSessionImpl.java:376) at org.apache.hive.service.cli.session.HiveSessionImpl.executeStatementAsync(HiveSessionImpl.java:363) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.apache.hive.service.cli.session.HiveSessionProxy.invoke(HiveSessionProxy.java:79) at org.apache.hive.service.cli.session.HiveSessionProxy.access$000(HiveSessionProxy.java:37) at org.apache.hive.service.cli.session.HiveSessionProxy$1.run(HiveSessionProxy.java:64) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1628) at org.apache.hadoop.hive.shims.HadoopShimsSecure.doAs(HadoopShimsSecure.java:536) at org.apache.hive.service.cli.session.HiveSessionProxy.invoke(HiveSessionProxy.java:60) at com.sun.proxy.$Proxy22.executeStatementAsync(Unknown Source) at org.apache.hive.service.cli.CLIService.executeStatementAsync(CLIService.java:270) at org.apache.hive.service.cli.thrift.ThriftCLIService.ExecuteStatement(ThriftCLIService.java:401) at org.apache.hive.service.cli.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1313) at org.apache.hive.service.cli.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1298) 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$WorkerProcess.run(TThreadPoolServer.java:206) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

　　從日誌能夠清楚地看出，出現該錯誤的緣由是由於咱們建立的用戶沒有執行‘Create’操做的權限，因此咱們須要將權限授予該用戶。

解決辦法：

hive> set system:user.name=hadoop;

1.給當前用戶權限：

　　給用戶當前權限：

hive> grant create on database default to user hadoop;

  OK

  Time taken: 0.146 seconds

　　或者給用戶全部權限  ：

hive> grant all on database default to user hadoop;  OK Time taken: 0.146 seconds

2.在其餘有權限的數據庫裏建立表

　　好比 當前用戶在db1裏面有權限，而在default裏面是沒有的那麼能夠：

use db1; create table default.test ( name string );

　　這樣也能夠建立。

　　而後，咱們的問題就能獲得解決了！
