初始化sparkContext python时出现奇怪错误

Question

我一直在使用spark2.0.1，但是试图升级到更新的版本，即2.1.1，方法是将tar文件下载到本地并更改路径。在

但是，现在当我尝试运行任何程序时，它在sparkContext初始化时失败。i、 e

    sc = SparkContext()

我尝试运行的整个示例代码是：

^{pr2}$

我得到的例外是在开始时，即：

    Traceback (most recent call last):
      File "/home/vna/scripts/global_score_pipeline/test_code_here.py", line 47, in 
        sc = SparkContext()

        conf, jsc, profiler_cls)

      File "/opt/apps/spark-2.1.1-bin-hadoop2.7/python/pyspark/context.py", line 249, in _initialize_context

    : java.lang.NumberFormatException: For input string: "Ubuntu"
        at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

我不会在我的变量或ENV变量中传递Ubuntu。。在

我也尝试过更改sc=SparkContext（master='local'），但问题还是一样。在

请帮助确定此问题

编辑：火花的内容-默认值.conf在

    spark.master                     spark://master:7077
    # spark.eventLog.enabled           true
    # spark.eventLog.dir               hdfs://namenode:8021/directory

    spark.driver.memory              8g

您是否检查过配置文件（例如spark-defaults.conf）？对于需要整数的字段，这可能是解析错误。例如，如果您尝试设置spark.executor.cores Ubuntu，您可能会得到该异常。在
