49478188,MDU6SXNzdWU0OTQ3ODE4OA==,279,BUG: reindex method creates new dims/coords,4194485,closed,0,,836999,0,2014-11-20T01:29:21Z,2014-12-19T07:21:31Z,2014-12-19T07:21:31Z,NONE,,,,"If you reindex an xray dataset or dataarray with a coordinate with a different name, an extra dimension and coordinate is added to the xray object (with the name of the reindexing coordinate). Here's a simple example:

```
x1 = xray.DataArray(np.random.randn(5, 6, 7), dims=[""lon"", ""lat"", ""time""])
time2 = xray.DataArray([1, 3], dims=""time2"")
x2 = x1.reindex(time=time2)
```

x2 now has coordinates ""time"" and ""time2"".

I'm using xray version 0.3.1-4-gee1369f.

35760380,MDExOlB1bGxSZXF1ZXN0MTcxNTcyMjI=,162,Change np.isnan to pd.isnull in conventions.py to handle _FillValue = '',4194485,closed,0,,,1,2014-06-15T23:10:29Z,2014-06-15T23:16:48Z,2014-06-15T23:16:35Z,NONE,,0,pydata/xarray/pulls/162,"At a number of spots in conventions.py, np.isnan was being used
to check possible fill values.  However, np.isnan is not implemented
for string types.  So, I've replaced np.isnan with pd.isnull.

Alas, I haven't been able to update the tests to cover _FillValue = '',
because doing so would involve significant changes throughout the
code base.
