storm redis喷口元组毫无例外地丢失了

我有一个storm拓扑(1 worker)设置,其中spout(在java中)从redis中退出(使用blpop)事件并传输到Bolt。但有一个观察结果是,当有超过200万的队列并且在storm nimbus/主管/Zookeeper/工作人员日志中未发现警告/异常时,bolt未收到一些事件(在clojure中,6个喷口螺纹,50个螺栓螺纹)。
在本地,此场景不使用虚拟数据进行复制。集群中没有网络延迟/数据包丢失。平均处理延迟是100毫秒。如何找到原因来解决它的生产。

(ns event-processor
  (:import [backtype.storm StormSubmitter LocalCluster]
           java.util.UUID
           storm_jedis.RedisQueueSpout
           )
  (:use [backtype.storm clojure config])
  (:require [clojure.tools.logging :as log])
  (:require [clj-redis.client :as redis])
  (:import (redis.clients.jedis Jedis JedisPool JedisPoolConfig))
  (:gen-class))

(defmacro process-event [tuple]
    (log/info "processing event")
    )

(defbolt execute-ls-closure ["word"] {:prepare true}
  [conf context collector]
  (let [counts (atom {})]

    (bolt
     (execute [tuple]
       (let [
        timestart (. System currentTimeMillis)
        tuple-message (.get (get tuple "message") 0)
        string-to-emit (process-event tuple)
        ]
        (emit-bolt! collector [string-to-emit] :anchor tuple)
        (ack! collector tuple)
        )))))

(defn mk-topology []

  (topology
   ;{"1" (spout-spec sentence-spout)
   {"1" (spout-spec redis-spout :p 6)
                     }
   {"3" (bolt-spec {"1" :shuffle }
                   execute-ls-closure
                   :p 50)
                   }))

(defn run-local! []
  (let [cluster (LocalCluster.)]
    (.submitTopology cluster "word-count" {TOPOLOGY-DEBUG true} (mk-topology))
    (Thread/sleep 10000)
    (.shutdown cluster)
    ))

(defn submit-topology! [name]
  (StormSubmitter/submitTopology
   name
   {TOPOLOGY-DEBUG true
    TOPOLOGY-WORKERS 1}
   (mk-topology)))

(defn -main
  ([]
   (run-local!))
  ([name]
   (submit-topology! name)))

如果它不会太慢您的拓扑结构,您可以使用启用调试日志记录 Config.setDebug(true) https://github.com/apache/storm/blob/f2ced23fa4e3f699558663baef4ee582ee148fa2/storm-client/src/jvm/org/apache/storm/config.java#l1763.
否则,我会尝试在bolt中添加一些调试日志记录,并为redis喷口启用日志记录,以确定元组是在风暴中丢失还是在redis集成中丢失。
我还注意到你使用的是旧的风暴版本。你可以尝试升级。
