我尝试按照this教程中的步骤在R中安装并启动h2o并到达此处：
> h2o.init(nthreads=-1)
H2O is not running yet, starting it now...
Note: In case of errors look at the following log files:
/home/pal/tmp/Rtmp8q7r3M/h2o_pal_started_from_r.out
/home/pal/tmp/Rtmp8q7r3M/h2o_pal_started_from_r.err
java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b114)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b56, mixed mode)
Starting H2O JVM and connecting: ... Connection successful!
R is connected to the H2O cluster:
H2O cluster uptime: 3 seconds 258 milliseconds
H2O cluster version: 3.8.2.8
H2O cluster name: H2O_started_from_R_pal_hmx971
H2O cluster total nodes: 1

H2O Connection ip: localhost
H2O Connection port: 54321
H2O Connection proxy: NA
R Version: R version 3.2.2 (2015-08-14)
然而，在此之后我没有看到通常的>以便我可以启动类型命令，此时它已停滞不前。你有什么想法怎么办？
