Hi,


I am new to Spark.I found using HiveContext we can connect to hive and run
HiveQLs. I run it and it worked.

My doubt is when we are using hiveContext and run hive query like(select
distinct column from table).

how it will perform it will take all data stored in hdfs into spark
engine(memory) and perform (select distinct column from table) or
it will give to hive and get result from hive.?



Thanks
