             Summary: Show timeseries produces incomplete result
                 Key: IOTDB-2010
                 URL: https://issues.apache.org/jira/browse/IOTDB-2010
             Project: Apache IoTDB
          Issue Type: Bug
            Reporter: Zhong Wang


In cluster mode, exceptions are omitted when getting the metadata of time series, which results in incomplete results.

In CMManager#showTimeseries:

{code:java}
    List<Future<Void>> futureList = new ArrayList<>();
    for (PartitionGroup group : globalGroups) {
      futureList.add(
          pool.submit(
              () -> {
                try {
                  showTimeseries(group, plan, resultSet, context);
                } catch (CheckConsistencyException | MetadataException e) {
                  logger.error("Cannot get show timeseries result of {} from {}", plan, group);
                }
                return null;
              }));
    }
{code}

A better way is to throw the exception if it cannot be handled by the system.
