> add oracle hint optimizer
> -------------------------
>
> Key: SPARK-14621
> URL: https://issues.apache.org/jira/browse/SPARK-14621
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.0
> Reporter: Qingyang Hong
> Priority: Minor
>
> Current SQL parser in SparkSQL can't identify hint optimizer in query, e.g.
> SELECT /*+index(o IDX_BILLORDER_SEND_UPDATE)+*/ ID, BILL_CODE, DATE FROM
> BILL_TABLE. It is necessary to add such feature which will increase query
> efficiency.
