Thanks for your fast replies.
I was wrong about HiveContext.
val hive = new org.apache.spark.sql.hive.HiveContext(sc)
var sample = hive.hql("select * from sample10")
var countHive = sample.count()
hive.registerRDDAsTable(sample,"temp")
hive.sql("select * from temp").count()
It works so fine.
Thanks,
Kevin
