pushcol on distributed table

[jstrube]

trafficstars

I'm trying to add a column to a distributed table, but the documentation doesn't seem to apply in this case:

momentum_noPhotoMuons = map(i->sqrt(i.px^2+i.py^2+i.pz^2), noPhotonMuons)
Dagger.DArray{Float64,1,JuliaDB.##58#60}(175723,)

Using a pushcol on this variable fails:

pushcol(noPhotonMuons, :momentum, momentum_noPhotoMuons)
MethodError: Dagger.distribute(::Dagger.DArray{Int64,1,JuliaDB.##58#60}, ::Dagger.DomainBlocks{1}) is ambiguous. Candidates:
  distribute(source, rowgroups::AbstractArray) in IterableTables at /home/ilc/jstrube/.julia/v0.6/IterableTables/src/integrations/juliadb.jl:19
  distribute(x::AbstractArray, dist) in Dagger at /home/ilc/jstrube/.julia/v0.6/Dagger/src/array/darray.jl:390
Possible fix, define
  distribute(::AbstractArray, ::AbstractArray)

While this is no doubt a bug, I'd be happy to work around this for the time being. All I want is to make a histogram of the Dagger.DArray, but I don't understand the data type. Could you please suggest how I can histogram that array?
