Review request for hive and Amareshwari Sriramadasu.


Changes
-------

added test cases for taskstatus


Bugs: HIVE-4570
    https://issues.apache.org/jira/browse/HIVE-4570


Repository: hive-git


Description
-------

Driver maintains list of running and runnable tasks although that info is not exposed outside.
It's kept locally in the driver's execute method. We can add Driver.getTaskStatuses() to return
status on all tasks (both running and runnable). Similarly, start and completion times for
operations.

Proposed changes are :

struct TGetOperationStatusResp {
  1: required TStatus status
  2: optional TOperationState operationState

  // If operationState is ERROR_STATE, then the following fields may be set
  // sqlState as defined in the ISO/IEF CLI specification
  3: optional string sqlState

  // Internal error code
  4: optional i32 errorCode

  // Error message
  5: optional string errorMessage

  // List of statuses of sub tasks
  6: optional string taskStatus

  // When was the operation started
  7: optional i64 operationStarted
  // When was the operation completed
  8: optional i64 operationCompleted

}
