@xnang

無背景，無程序，請問你讓我怎么幫你看？

安裝你說的步驟搭建了服務，所有的代碼都是example里面的，生產端可以正常寫入數據，返回類似Send message successfully,sent to -1-0 這樣的提示。消費端通過SyncConsumer這個類只能取出部分數據，比如寫入5條只能取到部分幾條使用AsyncConsumer.java
log4j在debug模式下出現了上面評論的那個異常錯誤

@xnang

從堆棧來看，明顯不是example的代碼，你自己寫的或者修改的吧。

從錯誤來看，應該是因為消費者的zk配置問題，請看example代碼。

SyncConsumer不是只能取出部分數據，可能是因為你沒有遞增offset，或者服務端延遲force的問題。

能告訴下你的郵箱么？我們發郵件交流吧。謝謝！
