Rajat Khandelwal updated LENS-423:
----------------------------------
Issue Type: Sub-task (was: Improvement)
Parent: LENS-657
> Cleanup of cube metadata classes.
> ----------------------------------
>
> Key: LENS-423
> URL: https://issues.apache.org/jira/browse/LENS-423
> Project: Apache Lens
> Issue Type: Sub-task
> Reporter: Rajat Khandelwal
>
> Just one thing for now. Can create subtasks if more come to mind
> 1. Eliminate null checks, particularly in member variables. Use Null design
> pattern wherever required.
> 2. Use CaseInsensitiveHashMap in cache objects in CubeMetastoreClient
> 3. Contract: functions like getAllDimensions from CubeMetastoreClient should
> never return null. Empty collection is okay
