>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.1

>
> SImply the *getOperationType* method in `org.apache.hive.service.cli.OperationType`.
>  Introduce a *HashMap* to cache the existed enumeration types, so as to avoid a linear search in a for loop.
>  `*OperationType.getOperationType*` can be called in OperationHandler.constructor:
>  
> {code:java}
>  
> public OperationHandle(TOperationHandle tOperationHandle, TProtocolVersion protocol) {
>   super(tOperationHandle.getOperationId());
>   this.opType = OperationType.getOperationType(tOperationHandle.getOperationType());
>   this.hasResultSet = tOperationHandle.isHasResultSet();
>   this.protocol = protocol;
> }
>  
> {code}
> `*OperationHandle* ` is widely used, It's better to improve the execution efficiency of `OperationType.getOperationType`
