Question

Hy，

我已多次运行Spark（Spyder IDE）。今天我收到了这个错误（代码是一样的）

from py4j.java_gateway import JavaGateway
gateway = JavaGateway()

os.environ['SPARK_HOME']="C:/Apache/spark-1.6.0"
os.environ['JAVA_HOME']="C:/Program Files/Java/jre1.8.0_71"
sys.path.append("C:/Apache/spark-1.6.0/python/")
os.environ['HADOOP_HOME']="C:/Apache/spark-1.6.0/winutils/"

from pyspark import SparkContext
from pyspark import SparkConf

conf = SparkConf()
    The system cannot find the path specified.
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "C:\Apache\spark-1.6.0\python\pyspark\conf.py", line 104, in __init__
        SparkContext._ensure_initialized()
      File "C:\Apache\spark-1.6.0\python\pyspark\context.py", line 245, in _ensure_initialized
        SparkContext._gateway = gateway or launch_gateway()
      File "C:\Apache\spark-1.6.0\python\pyspark\java_gateway.py", line 94, in launch_gateway
        raise Exception("Java gateway process exited before sending the driver its port number")
    Exception: Java gateway process exited before sending the driver its port number

出了什么问题？谢谢你的时间。

好的......有人在VirtualMachine中安装了新的java版本。我只是改变了这个

 <mvc:annotation-driven/>  
 <bean name="viewResolver"  
class="org.springframework.web.servlet.view.BeanNameViewResolver"/>  
 <bean name="jsonTemplate"  
class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>

再次运作。为你的时间而战。
