Read data with Spark, how to control coalesce partitions?


(Thomas Decaux) #1

Reading data with Spark (1.6) to elasticseach (2.4) in Java with

JavaEsSpark.esRDD

I am wondering how coalesce is achieved ? (I mean how distribution is done ?)

If it's possible to select a field as distribution key ?

Thanks you,
