能了一下午终于把hive搞好了,其中出现很多的问题
1、hadoop和hive的版本问题,最好上网查一查,走很多的弯路啊。hadoop重装了,hive用了两个0.7.1和0.11和0.12,最后是0.12搞定。2、遇到一个问题用了我将近二个小时才解决,分享下:hive> show tables; FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient 这个问题上网查了很多的资料各种的方法都有,自己都试一试,都不符合自己的东西。解决方法:cd ${HIVE_HOME}/bin ./hive -hiveconf hive.root.logger=DEBUG,console粗无提示如下: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient at org.apache.hadoop.hive.ql.metadata.Hive.getAllDatabases(Hive.java:1074) at org.apache.hadoop.hive.ql.exec.DDLTask.showDatabases(DDLTask.java:2198) at org.apache.hadoop.hive.ql.exec.DDLTask.execute(DDLTask.java:328) at org.apache.hadoop.hive.ql.exec.Task.executeTask(Task.java:151) at org.apache.hadoop.hive.ql.exec.TaskRunner.runSequential(TaskRunner.java:65) at org.apache.hadoop.hive.ql.Driver.launchTask(Driver.java:1414) at org.apache.hadoop.hive.ql.Driver.execute(Driver.java:1192) at org.apache.hadoop.hive.ql.Driver.runInternal(Driver.java:1020) at org.apache.hadoop.hive.ql.Driver.run(Driver.java:888) at org.apache.hadoop.hive.cli.CliDriver.processLocalCmd(CliDriver.java:259) at org.apache.hadoop.hive.cli.CliDriver.processCmd(CliDriver.java:216) at org.apache.hadoop.hive.cli.CliDriver.processLine(CliDriver.java:413) at org.apache.hadoop.hive.cli.CliDriver.executeDriver(CliDriver.java:781) at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:675) at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:614) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:212)Caused by: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient at org.apache.hadoop.hive.metastore.MetaStoreUtils.newInstance(MetaStoreUtils.java:1212) at org.apache.hadoop.hive.metastore.RetryingMetaStoreClient.<init>(RetryingMetaStoreClient.java:62) at org.apache.hadoop.hive.metastore.RetryingMetaStoreClient.getProxy(RetryingMetaStoreClient.java:72) at org.apache.hadoop.hive.ql.metadata.Hive.createMetaStoreClient(Hive.java:2372) at org.apache.hadoop.hive.ql.metadata.Hive.getMSC(Hive.java:2383) at org.apache.hadoop.hive.ql.metadata.Hive.getAllDatabases(Hive.java:1072) ... 19 moreCaused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at org.apache.hadoop.hive.metastore.MetaStoreUtils.newInstance(MetaStoreUtils.java:1210) ... 24 moreCaused by: MetaException(message:Version information not found in metastore. ) at org.apache.hadoop.hive.metastore.ObjectStore.checkSchema(ObjectStore.java:5638) at org.apache.hadoop.hive.metastore.ObjectStore.verifySchema(ObjectStore.java:5622) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.hive.metastore.RetryingRawStore.invoke(RetryingRawStore.java:124) at $Proxy11.verifySchema(Unknown Source) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.getMS(HiveMetaStore.java:403) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.createDefaultDB(HiveMetaStore.java:441) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.init(HiveMetaStore.java:326) at org.apache.hadoop.hive.metastore.HiveMetaStore$HMSHandler.<init>(HiveMetaStore.java:286) at org.apache.hadoop.hive.metastore.RetryingHMSHandler.<init>(RetryingHMSHandler.java:54) at org.apache.hadoop.hive.metastore.RetryingHMSHandler.getProxy(RetryingHMSHandler.java:59) at org.apache.hadoop.hive.metastore.HiveMetaStore.newHMSHandler(HiveMetaStore.java:4060) at org.apache.hadoop.hive.metastore.HiveMetaStoreClient.<init>(HiveMetaStoreClient.java:121) ... 29 more最后找到答案了:将hive.site.xml文件中的<property> <name>hive.metastore.schema.verification</name> <value>true</value> <description> </description></property>改为falseok了,希望对大家有帮助。
