["Tom Augspurger (JIRA)" <ji...@apache.org>]

Tom Augspurger created ARROW-1557:
-------------------------------------

             Summary: pyarrow.Table.from_arrays doesn't validate names length
                 Key: ARROW-1557
                 URL: https://issues.apache.org/jira/browse/ARROW-1557
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.7.0
            Reporter: Tom Augspurger
            Priority: Minor


pa.Table.from_arrays doesn't validate that the length of {{arrays}} and {{names}} matches. I think this should raise with a {{ValueError}}:

{{
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'
}}

(This is my first time using JIRA, hopefully I didn't mess up too badly)
