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/
