Examples of ChunkReceivedCallback

org.apache.spark.network.client.ChunkReceivedCallback
Callback for the result of a single chunk result. For a single stream, the callbacks are guaranteed to be called by the same thread in the same order as the requests for chunks were made. Note that if a general stream failure occurs, all outstanding chunk requests may be failed.

Examples of org.apache.spark.network.client.ChunkReceivedCallback

          long streamId = (Long) invocation.getArguments()[0];
          int myChunkIndex = (Integer) invocation.getArguments()[1];
          assertEquals(123, streamId);
          assertEquals(expectedChunkIndex.getAndIncrement(), myChunkIndex);


          ChunkReceivedCallback callback = (ChunkReceivedCallback) invocation.getArguments()[2];
          ManagedBuffer result = blockIterator.next();
          if (result != null) {
            callback.onSuccess(myChunkIndex, result);
          } else {
            callback.onFailure(myChunkIndex, new RuntimeException("Failed " + myChunkIndex));
          }
        } catch (Exception e) {
          e.printStackTrace();
          fail("Unexpected failure");
        }
