Question

我正在尝试安装Apache Toree内核以实现火花兼容性，并且我遇到了一个奇怪的环境消息。这是我遵循的过程：

使用Jupyter 4.1.0安装最后一个Anaconda版本
运行：pip install --pre toree
运行：jupyter toree install --interpreters = PySpark，SparkR，Scala，SQL

只对Scala Kernel真正感兴趣，但我安装了所有解释器。操作系统是Windows 7，没有选择使用虚拟机或Linux。

这是我修改为使用cygwin执行run.sh bash脚本的kernel.json文件：

{
  "language": "scala", 
  "display_name": "Apache Toree - Scala", 
  "env": {
    "__TOREE_SPARK_OPTS__": "", 
    "SPARK_HOME": "C:\\CDH\\spark", 
    "__TOREE_OPTS__": "", 
    "DEFAULT_INTERPRETER": "Scala", 
    "PYTHONPATH": "C:\\CDH\\spark\\python:C:\\CDH\\spark\\python\\lib\\py4j-0.8.2.1-src.zip", 
    "PYTHON_EXEC": "python"
  }, 
  "argv": [
    "C:\\cygwin64\\bin\\mintty.exe","-h","always","/bin/bash","-l","-e","C:\\ProgramData\\jupyter\\kernels\\apache_toree_scala\\bin\\run.sh", 
    "--profile", 
    "{connection_file}"
  ]
}

运行jupyter时，内核停止并显示错误：

TypeError: environment can only contain strings

我运行了命令isolated：

C:\\cygwin64\\bin\\mintty.exe -h always /bin/bash -l -e C:\\ProgramData\\jupyter\\kernels\\apache_toree_scala\\bin\\run.sh

它有效。它只在jupyter服务器执行的上下文中失败。

有没有人成功在Window机器上运行这个内核？

Answer 1

我编写了自己的（hacky）run.cmd并设法使用Spark 2.2.0和toree-assembly-0.2.0.dev1-incubating-SNAPSHOT使其工作。我在TOREE-399 ticket上发布了我的解决方案。

Run.cmd如下：

@echo off

set PROG_HOME=%~dp0..

if not defined SPARK_HOME (
  echo SPARK_HOME must be set to the location of a Spark distribution!
  exit 1
)

REM disable randomized hash for string in Python 3.3+
set PYTHONHASHSEED=0

REM The SPARK_OPTS values during installation are stored in __TOREE_SPARK_OPTS__. This allows values to be specified during
REM install, but also during runtime. The runtime options take precedence over the install options.

if not defined SPARK_OPTS (
  set SPARK_OPTS=%__TOREE_SPARK_OPTS__%
) else (
  if "%SPARK_OPTS%" == "" (
    set SPARK_OPTS=%__TOREE_SPARK_OPTS__%
  )
)

if not defined TOREE_OPTS (
  set TOREE_OPTS=%__TOREE_OPTS__%
) else (
  if "%TOREE_OPTS%" == "" (
    set TOREE_OPTS=%__TOREE_OPTS__%
  )
)

echo Starting Spark Kernel with SPARK_HOME=%SPARK_HOME%

REM This doesn't work because the classpath doesn't get set properly, unless you hardcode it in SPARK_SUBMIT_OPTS using forward slashes or double backslashes, but then you can't use the SPARK_HOME and PROG_HOME variables.
REM set SPARK_SUBMIT_OPTS=-cp "%SPARK_HOME%\conf\;%SPARK_HOME%\jars\*;%PROG_HOME%\lib\toree-assembly-0.2.0.dev1-incubating-SNAPSHOT.jar" -Dscala.usejavacp=true
REM set TOREE_COMMAND="%SPARK_HOME%\bin\spark-submit.cmd" %SPARK_OPTS% --class org.apache.toree.Main %PROG_HOME%\lib\toree-assembly-0.2.0.dev1-incubating-SNAPSHOT.jar %TOREE_OPTS% %*

REM The two important things that we must do differently on Windows are that we must add toree-assembly-0.2.0.dev1-incubating-SNAPSHOT.jar to the classpath, and we must define the java property scala.usejavacp=true.
set TOREE_COMMAND="%JAVA_HOME%\bin\java" -cp "%SPARK_HOME%\conf\;%SPARK_HOME%\jars\*;%PROG_HOME%\lib\toree-assembly-0.2.0.dev1-incubating-SNAPSHOT.jar" -Dscala.usejavacp=true -Xmx1g org.apache.spark.deploy.SparkSubmit %SPARK_OPTS% --class org.apache.toree.Main %PROG_HOME%\lib\toree-assembly-0.2.0.dev1-incubating-SNAPSHOT.jar %TOREE_OPTS% %*

echo.
echo %TOREE_COMMAND%
echo.

%TOREE_COMMAND%

应该放入run.cmd文件 C：\ ProgramData \ jupyter \内核\ apache_toree_scala \ BIN \
另外，你需要在上面的文件夹中编辑kernel.json来进行更改 run.sh to run.cmd。
如果您想允许安装额外的在Toree内核中，您还应该编辑toreeapp.py以将run.sh更改为 run.cmd。
我没有测试过IF语句是否正常工作。我怀疑他们会扼杀一些参数，因为批次缺乏强大的IF声明。

Answer 2

我有同样的问题使用：win on win 10，Anaconda，spark 2.0.2

这是我提出的解决方法：使用conda环境切换来设置环境变量而不是使用jupyter来设置它们

克隆一个单独的conda环境（http://conda.pydata.org/docs/using/envs.html#create-an-environment）
设置toree所需的环境变量（http://conda.pydata.org/docs/using/envs.html#windows）

jupyter notebook <root dir of notebooks>

您可以选择永久地从窗口设置toree变量并清空＆＃34; env＆＃34; kernel.json的字典 "env":{}

我想在使用pyspark时保持我的env变量分开

在Windows和Apache Toree Kernel上使用Jupyter以实现Spark兼容性
