Re: Forcing RDD computation with something else than count() ?

[Guillaume Pitel]

Thanks. So you mean that first() trigger the computation of the WHOLE  RDD ? That does not sound right, I thought it was lazy. Guillaume Hi, You can call less expensive operations like first or  take to trigger the computation. -- Guillaume PITEL, Président +33(0)6 25 48 86 80 eXenSa S.A.S. 41, rue Périer - 92120 Montrouge - FRANCE Tel +33(0)1 84 16 36 77 / Fax +33(0)9 72 28 37 05
