Kadir OZDEMIR commented on PHOENIX-5025:
----------------------------------------

[~apurtell], No, it was not intentional. In my environment, the Java version is 
set to 1.8 and I was under the impression that it is the right version for 
Phoenix. I will reopen the Jira and fix the incompatibility issue. It is 
interesting that Hadoop QA has not reported the problem. So, how should a 
developer find/check that he/she is using the right Java version for a given 
branch? Where is this info?

> A view without its base table is an orphan view. Since views are virtual 
> tables and their data is stored in their base tables, they are useless when 
> they become orphan. A base table can have child views, grandchild views and 
> so on. Due to some reasons/bugs, when a base table was dropped, its views 
> were not not properly cleaned up in the past. For example, the drop table 
> code did not support cleaning up grandchild views. This has been recently 
> fixed by PHOENIX-4764. Although PHOENIX-4764 prevents new orphan views due to 
> table drop operations, it does not clean up existing orphan views. It is also 
> believed that when the system catalog table was split due to a bug in the 
> past, it also contributed to creating orphan views as Phoenix did not support 
> splittable system catalog. Therefore, Phoenix needs a tool to clean up orphan 
> views.
