Re: Sorting a Table in Spark RDD

You could pluck out each column in separate rdds, sort them independently,
and zip them :)

Sorting a Table in Spark RDD

[Areg Baghdasaryan (BLOOMBERG/ 731 LEX -)]

Hello,

So I have crated a table in in RDD in spark in thei format:
col1col2
---
1. 10  11
2. 12  8
3.  9   13
4. 2   3

And the RDD is ristributed by the rows (rows 1, 2 on one node and rows 3 4 on 
another)
I want to sort each column of the table so that that output is the following:


col1col2
---
1. 2   3
2.  9   8
3.  10  11
4. 122 13

Is tehre a easy way to do this with spark RDD? The only way that i can think of 
so far is to transpose the table somehow..

Thanks
Areg
