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

             Summary: pyspark.sql.createDataFrame does not infer data type of parsed TSV
                 Key: SPARK-9807
                 URL: https://issues.apache.org/jira/browse/SPARK-9807
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 1.4.1
         Environment: CentOS 6, Python version 2.7.10, Scala version 2-10 
            Reporter: Karen Yin-Yee Ng


I tried parsing a space-separated file from HDFS.
And using `pyspark.sqlContext.createDataFrame` to convert the parsed lines to a PySpark DataFrame. However, all entries are parsed as string type regardless of what the correct data type is.

An example of my code and output can be found at:
