Error with save()

I tried to rebuild the example with the NY Taxi data from the PyData Conference. I downloaded the data, saved it on my Computer and tried the following code:

addprocs()
@everywhere using JuliaDB

cd("//Users/NY_Taxi")
path = pwd()

db = loadtable(path; indexcols=[1,2])
save(db, "mydata")

With the save I get the following error message:

On worker 3:

Any ideas?

Update: if I run it on a single core - it works without any problems ...

Strange, looks like it's unable to create the mydata directory. That or it's creating it a bunch of time after mkdir is called.

[HamletFr]

There is always than an empty directory ...

Can you check this now? Also, what's the JuliaDB version you're using?

I have the same error message with loadtable. I am not sure what the problem may be?
