Hi,
Can a tempTable registered in sqlContext be used to query inside forEachRDD
as shown below?
My requirement is that I have a set of data in the form of parquet inside
hdfs and I need to register the data
as a tempTable using sqlContext and query it inside forEachRDD as shown
below.
sqlContext.registerTempTable("tempTable")
messages.foreachRDD { rdd =>
val message:RDD[String] = rdd.map { y => y._2 }
sqlContext.sql("SELECT time,To FROM tempTable")
}
Thanks!
