Zheng Shao updated HIVE-862:
----------------------------
Resolution: Fixed
Fix Version/s: 0.6.0
Release Note: HIVE-862. CommandProcessor should return DriverResponse.
(Bill Graham via zshao) (was: Refactored CommandProcessor interface and it's
implementations to return CommandProcessorResponse object, instead of an int
response code. This is a non-backward compatible change, but one that's
necessary to better message clients.)
Hadoop Flags: [Reviewed]
Status: Resolved (was: Patch Available)
Committed. Thanks Bill!

> For reference here is how i want to use this:
> Currently:
> HWISessionItem.java
> private List<Integer> queryRet;
> private List<String> queries;
> public void runQuery() {
> //for each query in queries
> if (instanceof driver) {
> //other stuff here
> queryRet.add( qp.run(cmd) );
> } else {
> queryRet.add(proc.run(cmd_1) );
> }
> }
> So I would like to refactor and use DriverResponse.
> private List<DriverResponse> queryRet;
> private List<String> queries;
> public void runQuery() {
> //for each query in queries
>
> if (instanceof driver) {
> //other stuff here
> queryRet.add( qp.run(cmd) ); //<--- this is fine
> } else {
> queryRet.add(proc.run(cmd_1) ); <--this returns an int.
> }
> }
> {noformat}
