             Summary: Reading data frames via CSV - Allow to specify default 
value for integers
                 Key: SPARK-17012
                 URL: https://issues.apache.org/jira/browse/SPARK-17012
             Project: Spark
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: Aseem Bansal


Currently the option that we have in DataFrameReader is nullValue which allows 
us one default. But say in our data frame we have string and integers and we 
want to specify the default for strings and integers differently that is 
currently not possible.
