> org.apache.hadoop.hive.ql.exec.DDLTask handles DDL operations in Hive.
> Some operations (those exposed as REST API by Templeton) in this class, write
> a JSON object to stdout (on failure) which includes "error" and "errorCode"
> fields. "errorCode" is set to values like 404, 500, etc. i.e. Http Status
> codes. I believe this was done to support Templeton REST API. This is not
> the right place to introduce Http codes.
> DDLTask should use canonical error messages defined in
> org.apache.hadoop.hive.ql.ErrorMsg and propagate it up to HCatCli which can
> decide how to encode the error and to which stream. In particular it can
> create a parseable JSON object which Templeton can then interpret. JSON
> object can also be generated here for errors from the parser/resolver (e.g.
> trying to describe a table which doesn't exist).
> Then Templeton can map the canonical error code to appropriate Http Code.
