[GitHub] [druid] taborda opened a new issue #10507: Web console datasources screen is broken when there are datasources with no loaded segments (ArithmeticException)

taborda opened a new issue #10507:
URL: https://github.com/apache/druid/issues/10507


   ### Affected Version
   
   0.20.0
   
   ### Description
   
   When there is a datasource with no loaded segments, the Datasources screen on the Web Console fails to load.
   This can be reproduced if all the historical nodes are shutdown.
   
   The error is being caused by a division by zero:
   ```
   Error: Unknown exception
   
   / by zero
   
   java.lang.ArithmeticException
   ```

   The issue seems to be related with the recently added `avg_row_size` column:

   Commenting the code for this column allows the query to run:
