Zhong Wang reassigned IOTDB-2009:
---------------------------------
Assignee: Zhong Wang
> Previous filling produces incorrect result
> ------------------------------------------
>
> Key: IOTDB-2009
> URL: https://issues.apache.org/jira/browse/IOTDB-2009
> Project: Apache IoTDB
> Issue Type: Bug
> Components: Core/Cluster
> Reporter: Zhong Wang
> Assignee: Zhong Wang
> Priority: Major
>
> In cluster mode, exceptions that happen when fetching the latest data point
> are omitted.
> For example, in ClusterPreviousFill#configureFill:
> {code:java}
> @Override
> public void configureFill(
> PartialPath path,
> TSDataType dataType,
> long queryTime,
> Set<String> deviceMeasurements,
> QueryContext context) {
> try {
> fillResult =
> performPreviousFill(
> path, dataType, queryTime, getBeforeRange(),
> deviceMeasurements, context);
> } catch (StorageEngineException e) {
> logger.error("Failed to configure previous fill for Path {}", path, e);
> }
> }
> {code}
> Thus, the returned result may not be the latest data point. The correct way
> is to throw the exception if the system is not able to handle it.
