{code}
from pyspark.ml.feature import HashingTF
df = sqlContext.createDataFrame([(["foo", "bar"], )], ("keys", ))
transformer = HashingTF(inputCol="keys", outputCol="vec", numFeatures=5)
transformed = transformer.transform(df)
row = transformed.first()
row.vec # As expected
## SparseVector(5, {4: 2.0})
row[1] # Returns tuple
