Ashutosh Chauhan commented on HIVE-14048:
-----------------------------------------
Those fields are not of public api, there is no contract that we need to
deprecate them before removing them. Dependencies which are using non-public
apis need to update their source if they rely on non-public apis.
> patch for HIVE-4570 removes protected fields which can break dependencies

> URL: https://issues.apache.org/jira/browse/HIVE-14048
> Project: Hive
> Issue Type: Bug
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Critical
>
> The patch for HIVE-4570 removes protected fields like initialized, isDone,
> started etc and created a TaskState enum to represent these variables. Since
> these fields which were removed were marked protected, class which can extend
> Task.java (or DDLTask.java) will fail to compile once they get this patch.
> The protected fields should probably be marked deprecated instead of removing
> them directly since it could break outside dependencies.
