-------------------------------
    Resolution: Not A Problem

> 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.
