the class GenerateClientUsageExample method queryClient.

public void queryClient() throws Exception {
    // Construct the client used to interact with CDAP
    QueryClient queryClient = new QueryClient(clientConfig);
    // Perform an ad-hoc query using the Purchase example
    ListenableFuture<ExploreExecutionResult> resultFuture = queryClient.execute(NamespaceId.DEFAULT, "SELECT * FROM dataset_history WHERE customer IN ('Alice','Bob')");
    ExploreExecutionResult results = resultFuture.get();
    // Fetch schema
    List<ColumnDesc> schema = results.getResultSchema();
    String[] header = new String[schema.size()];
    for (int i = 0; i < header.length; i++) {
        ColumnDesc column = schema.get(i);
        // Hive columns start at 1
        int index = column.getPosition() - 1;
        header[index] = column.getName() + ": " + column.getType();
    }
}
