Hi bit1129, 1, hive in spark assembly removed most dependencies of hive on Hadoop to avoid conflicts. 2, this hive is used to run some native command, which does not rely on spark or mapreduce.

I think hive in the spark assembly is not the same thing as Hive On Spark(Hive On Spark, is meant to run hive using spark execution engine). So, my question is: 1. What is the difference between Hive in the spark assembly and Hive on Hadoop? 2. Does Hive in the spark assembly use Spark execution engine or Hadoop MR engine? Thanks. ________________________________ bit1...@163.com<mailto:bit1...@163.com>
