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

Question

I've a configured Hadoop 0.23 on my local box and got it work with a simple map-reduce wordcount program. I Have configured Hive to work with it. All the DDL queries works fine. But when i fire queries that have aggregates (which will trigger Map-educe jobs)

Answer 1

You should create the same file /Users/varadham/projects/hadoop/hive/lib/hive-builtins-0.9.0.jar in your hadoop file system. Then it should work.

Answer 2

确保HDFS中包含jar。
