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

Question

我在本地機器上配置了Hadoop 0.23，並使其與一個簡單的map-reduce wordcount程序一起工作。 我已經配置Hive來使用它。 所有的DDL查詢都可以正常工作。 但是當我觸發具有聚合的查詢時（這將觸發Map-educe作業）

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

您應該在hadoop文件系統中創建相同的文件/Users/varadham/projects/hadoop/hive/lib/hive-builtins-0.9.0.jar。 然后它應該工作。

Answer 2

確保HDFS中包含jar。
