在R中安装h20时出错

我在R中安装h2o包时出现此错误。请参见下面的内容

     Error in h2o.init() : H2O failed to start, stopping execution.
      In addition: Warning message:
     running command 'curl 'http://localhost:54321'' had status 127 

    Note:  In case of errors look at the following log files:

    java version "9.0.1"
    Java(TM) SE Runtime Environment (build 9.0.1+11)
    Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)

   Starting H2O JVM and connecting: 
  ............................................................ 
   [1] "localhost"
   [1] 54321
   [1] TRUE
   [1] -1
   [1] "Failed to connect to localhost port 54321: Connection refused"
   [1] 127

有什么提示吗？谢谢

看来JDK 9不受支持。它的可能副本似乎不支持JDK 9。可能重复的
