----------------------------------------

             Summary: Inconsistent resulting type during casting in pa.array() when mask is
present
                 Key: ARROW-5208
                 URL: https://issues.apache.org/jira/browse/ARROW-5208
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.13.0
            Reporter: Artem KOZHEVNIKOV


I would expect Int64Array type in all cases below :
{code:java}
pa.array([4, None, 4, None], mask=np.array([False, True, False, True]))             
                                                            
       
<pyarrow.lib.Int64Array object at 0x91fad3a98>

[

  4,

  null,

  4,

  null

]


pa.array([4, None, 4, 'rer'], mask=np.array([False, True, False, True]))            
                                                           
           
<pyarrow.lib.Int64Array object at 0x9201f23b8>

[

  4,

  null,

  4,

  null

]

pa.array([4, None, 4, 3.], mask=np.array([False, True, False, True]))             
                                                           
              <pyarrow.lib.DoubleArray object at 0x91fab7638> [   4,   null,
  4,   null ]{code}
