The following files are suggested for removal:

- ql/src/java/org/apache/hadoop/hive/ql/plan/ExplosionDesc.java
- ql/src/java/org/apache/hadoop/hive/ql/plan/SchemaDesc.java
I've checked each and every one of them, and none of them is referenced by any
[https://github.com/apache/]* projects, or any
[https://github.infra.cloudera.com/]* projects. Even their name is not present
at all in any file other then themselves. [~gopalv], [~vgarg] because of this
I suggest not to deprecate them, but delete them directly. Please let me know
what you think.
