Some textual scholars regard the two accounts as different versions of the same events at Meribah, with the version in the Book of Exodus being from the JE source, and the version in the Book of Numbers being from the Priestly Source; the latter account, like the Priestly Source in general, is considered to be an attempt to supplant the JE version of the narrative, which doesn't treat Aaron as being as important as the Aaronid writer of the Priestly Source would have liked.
