Sean Owen updated SPARK-5918:
-----------------------------
    Component/s: SQL

> Spark Thrift server reports metadata for VARCHAR column as STRING in result 
> set schema
> --------------------------------------------------------------------------------------
>
>                 Key: SPARK-5918
>                 URL: https://issues.apache.org/jira/browse/SPARK-5918
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.1.1, 1.2.0
>            Reporter: Holman Lan
>
> This is reproducible using the open source JDBC driver by executing a query 
> that will return a VARCHAR column then retrieving the result set metadata. 
> The type name returned by the JDBC driver is VARCHAR which is expected but 
> reports the column type as string[12] and precision/column length as 
> 2147483647 (which is what the JDBC driver would return for STRING column) 
> even though we created a VARCHAR column with max length of 1000.
> Further investigation indicates the GetResultSetMetadata Thrift client API 
> call returns the incorrect metadata.
> We have confirmed this behaviour in  versions 1.1.1 and 1.2.0. We have not 
> yet tested this against 1.2.1 but will do so and report our findings.
