Description
After the "Execute" call is made from an HS2 client, the "GetResultsMetaData" is called, followed by the "Fetch" call.
If the "Execute" sets the error state to "ERROR" before the GetResultsMetaData has been called, an exception is thrown since it only expects the state to be RUNNING or FINISHED.
The code affecting it is SQLOperation:
@Override public TableSchema getResultSetSchema() throws HiveSQLException { // Since compilation is always a blocking RPC call, and schema is ready after compilation, // we can return when are in the RUNNING state. assertState(Arrays.asList(OperationState.RUNNING, OperationState.FINISHED)); if (resultSchema == null) { resultSchema = new TableSchema(driver.getSchema()); } return resultSchema; }
Adding ERROR to "assertState" should fix the problem.
