> Having rollback for DDLs was a bad idea.
> and it turns out to be an unexpected behavior for the user.
> DDLs only have transient errors (e.g. zk, hdfs, meta down)
> if we abort/rollback on a transient failure the user will get a failure,
> and it is not clear why the user needs to retry the command when the system
> can do that.
