> 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(

>                 } 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.
