Hadoop != M/R, FWIW. M/R support is left in Yarn for backwards compatibility mostly.

If by M/R you mean Hadoop - Cloudera has done no such thing, their largest customer base is Hadoop.

As to "paradigm shift", we're so early in this that I don't think there even is a paradigm to shift.

Sure, "we're 100% behind Impala", "oops, sorry, now it's Spark" - give them a few months and they'll change their mind to something else again. :)
