--------------------------------------
Hi Shunyu:
I think you are right about the parser part, but on top of the parser, quite a
few other places also need new code to handle the 'CHAR' type.
I was looking at the entire stack trying not to miss anything, please look at
my proposed change and see whether it looks good to you.
Thanks!
> spark-sql do not support for column datatype of CHAR
> ----------------------------------------------------
>
> Key: SPARK-11628
> URL: https://issues.apache.org/jira/browse/SPARK-11628
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.1
> Reporter: zhangshunyu
> Labels: features
>
> In spark-sql when we create a table using the command as follwing:
> "create table tablename(col char(5));"
> Hive will support for creating the table, but when we desc the table:
> "desc tablename"
> spark will report the error：
> “org.apache.spark.sql.types.DataTypeException: Unsupported dataType:
> char(5). If you have a struct and a field name of it has any special
> characters, please use backticks (`) to quote that field name, e.g. `x+y`.
> Please note that backtick itself is not supported in a field name.”
