Hi , >I am new to Spark scala environment.Currently I am working on Discrete wavelet transformation algos on time series data. > I have to perform recursive additions on successive elements in RDDs. > for example > List of elements(RDDS) --a1 a2 a3 a4..... > level1 Tranformation --a1+a2 a3+a4 a1-a2 a3-a4 > level 2---(a1+a2)+(a3+a4) (a1+a2)-(a3+a4)
Is their a way to provide indexing to elements in distributed environment across nodes so that I know that i am referring to a2 after a1 ..I want to perform successive addition of only two elements and in a recursive manner .. Could you please help me in this aspect..I would be really thankful to you.. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Regarding-Successive-operation-on-elements-and-recursively-tp2826.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
