You could try [Elemental.jl](https://github.com/JuliaParallel/Elemental.jl): it plays nicely with [DistributedArrays.jl](https://github.com/JuliaParallel/DistributedArrays.jl).

It seems like the QR isn’t currently available in the Julia package, but it is in [the underlying library](http://libelemental.org/documentation/0.85/lapack_like/factor/QR.html), so it it should be a matter of adding the necessary wrappers.
