Zhong Wang created IOTDB-2009:
---------------------------------
Summary: 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
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.
