Cheng Lian reassigned SPARK-5918:
---------------------------------
Assignee: Cheng Lian
> 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
> Assignee: Cheng Lian
>
> 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.
