>             Project: Kylin
>          Issue Type: Bug
>            Reporter: liyang
> Report by Jason Wang:
> I just finished building a cube in Kylin, and it was successful, but in the 
> Insight page, there is no tables, and if I submit a query, it fails with a 
> table not found error. Notice there are no tables in the left side of the 
> page. I noticed that, when I select the project in the page header, there was 
> a request made to path 
> “/kylin/api/tables_and_columns?project=DeviceMetrics_Prototype”, and the 
> response was an empty JSON array “[]”.
> The problem seems to be caused by stale L2 cache. 
> ProjectManager.isExposedTable() return false for the table.
> Realizing that, I restarted Kylin server, and the tables came up, and I can 
> query them without any problem. Please look into your cache update logic, 
> especially in the case where the cube building is taking extra-long time. In 
> this particular case, the cube build took 12 hours. When I experimented with 
> a smaller cube (40 minutes), I didn’t encounter this issue.
