Example 1 with RestClientException

use of org.apache.flink.runtime.rest.util.RestClientException in project flink by apache.

the class RestClient method parseResponse.

private static <P extends ResponseBody> CompletableFuture<P> parseResponse(JsonResponse rawResponse, JavaType responseType) {
    CompletableFuture<P> responseFuture = new CompletableFuture<>();

            responseFuture.completeExceptionally(new RestClientException(error.errors.toString(), rawResponse.getHttpResponseStatus()));
        } catch (JsonProcessingException jpe2) {
            // if this fails it is either the expected type or response type was wrong, most
            // likely caused
            // by a client/search MessageHeaders mismatch
            LOG.error("Received response was neither of the expected type ({}) nor an error. Response={}", responseType, rawResponse, jpe2);
            responseFuture.completeExceptionally(new RestClientException("Response was neither of the expected type(" + responseType + ") nor an error.", originalException, rawResponse.getHttpResponseStatus()));
