ProcessSimulator.killAllProcesses（line：78）NoSuchMethodError ConcurrentHashMap.keySet（）

Question

為什么？ 我第一次使用Storm（從Storm入門中學習）並運行成功，但發現NoSuchMethodError：

java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;

和

org.apache.storm.shade.org.apache.zookeeper.server.ServerCnxn$EndOfStreamException: Unable to read additional data from client sessionid 0x15b28de9a8b0011, likely client has closed socket

Answer 1

那可能是Java 8 <> 7不兼容的問題。 請。 檢查以下問題： ConcurrentHashMap使使用JDK 8編譯但針對JRE 7的應用程序崩潰
