> I have a legacy streaming cube, which has a design issue so I created a new
> version (changing encoding for a column). In order to query both historical
> and new data, I created a hybrid with them. The old cube stops and the new
> cube starts incremental building; At the begining the query is okay, it hits
> the hybrid and then fetch both hist and current data; but when running for
> some time, the query returns error, in the backend log I see error like
> "org.apache.hadoop.hbase.TableNotFoundException: KYLIN_C178KEQ2K0"; The table
> had been dropped after a merge, which means Kylin uses out of date info.
> After click "Reload metadata" button, the query goes well.
