-----------------------------------
Summary: HybridInstance cache wasn't cleaned when underlying Cube
be updated
Key: KYLIN-2499
URL: https://issues.apache.org/jira/browse/KYLIN-2499
Project: Kylin
Issue Type: Bug
Components: Metadata
Reporter: Shaofeng SHI
Assignee: Shaofeng SHI
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had been dropped after a merge, which means Kylin uses out of date info.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.
