             Summary: UpdateInputAccessTimeHook in Hive doesn't implement Hook interface so is it not usable?
                 Key: HIVE-17134
                 URL: https://issues.apache.org/jira/browse/HIVE-17134
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.1.1
            Reporter: Di Zhu


I try to run `set hive.exec.pre.hooks=org.apache.hadoop.hive.ql.hooks.UpdateInputAccessTimeHook;` firstly, and then it will complains **FAILED: Hive Internal Error: java.lang.ClassCastException(org.apache.hadoop.hive.ql.hooks.UpdateInputAccessTimeHook cannot be cast to org.apache.hadoop.hive.ql.hooks.Hook)** on any queries. I checked the [source code](https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/hooks/UpdateInputAccessTimeHook.java) of that class, which doesn't implement Hook interface as stated in the error. But all other class in the [same package](https://github.com/apache/hive/tree/master/ql/src/java/org/apache/hadoop/hive/ql/hooks) implements Hook interface. So am I using this class in the wrong way or it is a bug? Thanks.
