> Handle alter events when replicate to cluster with hive.strict.managed.tables

>            Assignee: Ashutosh Bapat

>
> Some of the events from Hive2 may cause conflicts in Hive3 
> (hive.strict.managed.tables=true) when applied. So, need to handle them 
> properly.
>  1. Alter table to convert non-acid to acid.
>  - Do not allow this conversion on source of replication if strict.managed is 
> false.
> 2. Alter table or partition that changes the location.
>  - For managed tables at source, the table location shouldn't be changed for 
> the given non-partitioned table and partition location shouldn't be changed 
> for partitioned table as alter event doesn't capture the new files list. So, 
> it may cause data inconsistsency. So, if database is enabled for replication 
> at source, then alter location on managed tables should be blocked.
>  - For external partitioned tables, if location is changed at source, the the 
> location should be changed for the table and any partitions which reside 
> within the table location, but not for the partitions which are not within 
> the table location. (may be we just need the test).
