             Summary: Wrong configuration 'groupid' to get lag for new kafka 
spout
                 Key: STORM-2568
                 URL: https://issues.apache.org/jira/browse/STORM-2568
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-core
    Affects Versions: 1.1.0
            Reporter: Haewan Jeong


Hello

I've tried to use storm-kafka-monitor, and it works fine on command line If I 
changed 'toollib/storm-kafka-monitor-*.jar' to 
'toollib/storm-kafka-monitor-1.1.0.jar'.

but it gives empty result when I call below api.
{code}
/api/v1/topology/:id/lag
...

{
"MySpoutName": {
"spoutLagResult": {},
"spoutId": "MySpoutName",
"spoutType": "KAFKA"
}
}
{code}

I think need to fix "groupid" to "group.id" in TopologySpoutLag.java

{code}
package org.apache.storm.utils;
public class TopologySpoutLag {
...
commands.add((String)jsonConf.get(configKeyPrefix + "groupid"));
{code}


{code}
package org.apache.storm.kafka.spout;
public class KafkaSpoutConfig<K, V> implements Serializable {
...
public String getConsumerGroupId() {
        return (String)this.kafkaProps.get("group.id");
    }
...
        public KafkaSpoutConfig.Builder<K, V> setGroupId(String id) {
            return this.setProp("group.id", id);
        }
{code}
