Subject Hive on Spark Engine versus Spark using Hive metastore
Date Tue, 02 Feb 2016 22:38:48 GMT
Hi,

 

My understanding is that with Hive on Spark engine, one gets the Hive
optimizer and Spark query engine

 

With spark using Hive metastore, Spark does both the optimization and query
engine. The only value add is that one can access the underlying Hive tables
from spark-sql etc

 

 

Is this assessment correct?

 

 

 

Thanks

 

Dr Mich Talebzadeh
