Comments:
this is not great because xfailing entire test. should figure out what actually is failing and only xfail that part.
I think fastparquet is using deps which cause an upgrade of numpy here.

```
package plan for installation in environment /Users/travis/miniconda3/envs/pandas:
The following NEW packages will be INSTALLED:
    arrow-cpp:      0.7.1-py35_2               conda-forge
    fastparquet:    0.1.3-py35_0               conda-forge
    feather-format: 0.3.1-py35_1               conda-forge
    llvmlite:       0.21.0-py35h3a66efe_0                 
    numba:          0.36.1-np113py35hd65e1c9_0            
    parquet-cpp:    1.3.0.post-2               conda-forge
    pyarrow:        0.7.1-py35_1               conda-forge
    thrift:         0.10.0-py35_0              conda-forge
The following packages will be UPDATED:
    numpy:          1.10.4-py35_nomkl_2                    [nomkl] --> 1.13.3-py35_nomklh6554414_0 [nomkl]
```

So easiest is to simply use a later version of numpy on this build. I will update.
I think this will fail until fastparquet does a release with https://github.com/dask/fastparquet/pull/264
yeah, going to move to 0.22.0
