Test result of python3 & spark 2.2.0 is here. I will check on python 2 in a
few minutes. I paste the whole command line output, it's a bit lengthy.
@HyukjinKwon could you please double check if my test is complete?
```python
>>> import array,sys
>>> from pyspark import *
>>> from pyspark.sql import *
>>>
>>> def assertCollectSuccess(typecode, value):
... row = Row(myarray=array.array(typecode, [value]))
... df = spark.createDataFrame([row])
... print(typecode)
... df.show()
...
>>> assertCollectSuccess('u',u'a')
