      Description

      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KYLIN_C178KEQ2K0"; The table had been dropped after a merge, which means Kylin uses out of date info.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.
