> Key: SPARK-10947
> URL: https://issues.apache.org/jira/browse/SPARK-10947
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.5.1
> Reporter: Ewan Leith
> Priority: Minor
> Labels: releasenotes
> Fix For: 1.6.0
>
>
> Currently, when a schema is inferred from a JSON file using
> sqlContext.read.json, the primitive object types are inferred as string,
> long, boolean, etc.
> However, if the inferred type is too specific (JSON obviously does not
> enforce types itself), this causes issues with merging dataframe schemas.
> Instead, we would like an option in the JSON inferField function to treat all
> primitive objects as strings.
> We'll create and submit a pull request for this for review.
