Question

我在本地方框上配置了Hadoop 0.23并使用简单的map-reduce wordcount程序。我已将Hive配置为使用它。所有DDL查询都可以正常工作。但是，当我触发具有聚合的查询（这将触发Map-educe作业）

Job Submission failed with exception 'java.io.FileNotFoundException(File does not exist: /Users/varadham/projects/hadoop/hive/lib/hive-builtins-0.9.0.jar)'

Answer 1

您应该在hadoop文件系统中创建相同的文件/Users/varadham/projects/hadoop/hive/lib/hive-builtins-0.9.0.jar。然后它应该工作。

Answer 2

确保你有HDFS中的jar。

Hive中的hive / lib / hive-builtins-0.9.0.jar的FileNotFoundException
