> pa.Table.from_arrays doesn't validate that the length of {{arrays}} and
> {{names}} matches. I think this should raise with a {{ValueError}}:
> {code}
> In [1]: import pyarrow as pa
> In [2]: pa.Table.from_arrays([pa.array([1, 2]), pa.array([3, 4])],
> names=['a', 'b', 'c'])
> Out[2]:
> pyarrow.Table
> a: int64
> b: int64
> In [3]: pa.__version__
> Out[3]: '0.7.0'
> {code}
> (This is my first time using JIRA, hopefully I didn't mess up too badly)
