我开发了storm拓扑来接收kafka经纪人在hortonworks上提供的jsonarray数据,
我不知道为什么我的kafkaspout不使用来自hdp中kafka代理的消息,但是成功提交了storm拓扑,但是当我可视化拓扑时:0%的数据已被使用!!
拓扑可视化
这是我的计划课:
public class ClientInfosSheme implements Scheme{
private static final long serialVersionUID = -2990121166902741545L;
private static final Logger LOG = Logger.getLogger(ClientInfosSheme.class);
public String codeBanque;
public String codeAgence;
public String codeGuichet;
public String devise;
public String numCompte;
public String codeClient;
public String codeOperation;
public String sensOperation;
public String montantOperation;
public String dateValeur;
public String dateComptable;
public String utilisateur;
public static final String CODEBANQUE="codeBanque";
public static final String CODEAGENCE="codeAgence";
public static final String CODEGUICHET="codeGuichet";
public static final String DEVISE="devise";
public static final String NUMCOMPTE="numCompte";
public static final String CODECLIENT="codeClient";
public static final String CODEOPERATION="codeOperation";
public static final String SENSOPERATION="sensOperation";
public static final String MONTANTOPERATION="montantOperation";
public static final String DATEVALEUR="dateValeur";
public static final String DATECOMPTABLE="dateComptable";
public static final String UTILISATEUR="utilisateur";
public List<Object> deserialize(byte[] bytes) {
try{
String clientInfos = new String(bytes, "UTF-8");
JSONArray JSON = new JSONArray(clientInfos);
for(int i=0;i<JSON.length();i++) {
JSONObject object_clientInfos=JSON.getJSONObject(i);
try{
//Récupérations des données
this.codeBanque=object_clientInfos.getString("codeBanque");
this.codeAgence=object_clientInfos.getString("codeAgence");
this.codeGuichet=object_clientInfos.getString("codeGuichet");
this.devise=object_clientInfos.getString("devise");
this.numCompte=object_clientInfos.getString("numCompte");
this.codeClient=object_clientInfos.getString("codeClient");
this.codeOperation=object_clientInfos.getString("codeOperation");
this.sensOperation=object_clientInfos.getString("sensOperation");
this.montantOperation=object_clientInfos.getString("montantOperation");
this.dateValeur=object_clientInfos.getString("dateValeur");
this.dateComptable=object_clientInfos.getString("dateComptable");
this.utilisateur=object_clientInfos.getString("utilisateur");
}
catch(Exception e)
{
e.printStackTrace();
}
}// End For Loop
} catch (JSONException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return new Values(codeBanque, codeAgence, codeGuichet, devise, numCompte, codeClient, codeOperation, sensOperation,
montantOperation,dateValeur, dateComptable,utilisateur);
}// End Function deserialize
public Fields getOutputFields() {
return new Fields(CODEBANQUE,CODEAGENCE,CODEGUICHET,DEVISE,NUMCOMPTE,
CODECLIENT,CODEOPERATION, SENSOPERATION,MONTANTOPERATION,DATEVALEUR,DATECOMPTABLE,UTILISATEUR);
}
}
以及属性文件:
# Broker host
kafka.zookeeper.host.port=sandbox.hortonworks.com
# Kafka topic to consume.
kafka.topic=INFOCLIENT
# Location in ZK for the Kafka spout to store state.
kafka.zkRoot=/client_infos_sprout
# Kafka Spout Executors.
spout.thread.count=1
当我使用另一个消费者时,存储在kafka代理中的数据如下:
[{"codeBanque":"xx","codeAgence":"yy","codeGuichet":"zz","devise":"tt"..},
{"codeBanque":"xx1","codeAgence":"yy1","codeGuichet":"zz1","devise":"tt1"..},
{"codeBanque":"xx2","codeAgence":"yy2","codeGuichet":"zz2","devise":"tt2"..}]
所以我的问题是为什么它不消费Kafka经纪人的信息?
求你了我需要帮助

正如您在日志中发现的那样,您的喷口不会“消费”消息,因为拓扑有一个错误并且没有确认元组-因此喷口将重放它们。这是工作的设计。
一旦拓扑结构稳定,您将观察到偏移量正在增加。在此之前,喷口将向拓扑发送消息,但您将无法观察结果。
如果没有看到calculclerib方法,以及它是如何集成到您的拓扑中的,我们将无法帮助您调试该方面。
