This is essentially saying that something you are importing in the ui code
(core.clj) is causing issues. I'm not totally sure which import it is, because
clojure is importing them dynamically. I would suggest that you change the
code from
```(ns backtype.storm.ui.core
(:use compojure.core)
...
(:import [backtype.storm.utils Utils])
...
(:gen-class))
```
to something like
```
(ns backtype.storm.ui.core
(:gen-class))
(use compojure.core)
...
(import [backtype.storm.utils Utils])
...```
This should give you a clue as to which import statement is causing the problem.

Really sorry for that. I will repost my question as follows.
Hi, I want to implement a feature in auto-tuning the max-spout-pending
parameter. (Yes, you already have known that this is the idea inspired by
Twitter's 2014 Sigmod paper) Now I want to put some configuration in the
defaults.yaml to control whether using the auto-tuning functionality and the
tuning interval. So I did that in defaults.yamltopology.max.spout.pending: null
topology.max.spout.pending.auto: false
topology.max.spout.pending.update.interval: 120
topology.state.synchronization.timeout.secs: 60And the corresponding code in
the Config.java is as follows:public static final String
TOPOLOGY_MAX_SPOUT_PENDING="topology.max.spout.pending";
public static final Object TOPOLOGY_MAX_SPOUT_PENDING_SCHEMA =
ConfigValidation.IntegerValidator;
public static final String
TOPOLOGY_MAX_SPOUT_PENDING_AUTO="topology.max.spout.pending.auto";
public static final Object TOPOLOGY_MAX_SPOUT_PENDING_AUTO_SCHEMA =
Boolean.class;
public static final String
TOPOLOGY_MAX_SPOUT_PENDING_UPDATE_INTERVAL="topology.max.spout.pending.update.interval";
public static final Object TOPOLOGY_MAX_SPOUT_PENDING_UPDATE_INTERVAL_SCHEMA =
ConfigValidation.IntegerValidator;
As I run the mvn compile
Maven gives me such errors

Because the suggestion of Clojure is such concise and abstract. I have spend
hours on this problem.
Any one has encountered this problem? Please help me kindly.
Thanks.
