可能的原因

刚开始我用伪分布模式没有提示这个错误,我配置了mapred-site.xml为local模式,但core-site.xml使用hdfs,从hdfs找不到这个文件。

可能的代码

 //ql/src/java/org/apache/hadoop/hive/ql/session/SessionState.java
 
   // Register the Hive builtins jar and all of its functions
    try {
      Class<?> pluginClass = Utilities.getBuiltinUtilsClass();
      URL jarLocation = pluginClass.getProtectionDomain().getCodeSource()
        .getLocation();
      add_builtin_resource(
        ResourceType.JAR, jarLocation.toString());
      FunctionRegistry.registerFunctionsFromPluginJar(
        jarLocation, pluginClass.getClassLoader());
      sessionFunctionRegistry.putAll(FunctionRegistry.getStaticFunctionRegistry());
    } catch (Exception ex) {
      throw new RuntimeException("Failed to load Hive builtin functions", ex);
    }

解决方法

方法一:
更改core.site.xml,把fs.default.name改成local

  <property>
    <name>fs.default.name</name>
    <value>file:///</value>
  </property>

方法二(没试过):
把hive-builtins包上传到提示的hdfs路径(我这里是/home/fatkun/hive-0.10.0-cdh4.3.0/lib/)
$ hadoop fs -mkdir /home/fatkun/hive-0.10.0-cdh4.3.0/lib/
$ hadoop fs -put $HIVE_HOME/lib/hive-builtins-*.jar /home/fatkun/hive-0.10.0-cdh4.3.0/lib/

我很好奇的问下,把fs.default.name改成file:///情况,我知道在实验环境可能没有事情,但是在服务器环境下,会没有事情吗
