pyspark 内核与 jupyter - 找不到内核

Question

我正在尝试在 jupyter 中使用 pyspark 内核。我对这两者都是新手，并且四处寻找尝试让 pyspark 2.1.0 在 jupyter 中工作。

我已经在 64 位 Ubuntu 16.04 LTS 上安装了 pyspark 2.1.0 和 anaconda3。我在 .bashrc 中设置了以下导出：

export SPARK_HOME=/usr/lib/spark
export PYSPARK_SUBMIT_ARGS="--master local[2] pyspark-shell"
export SBT_HOME=/usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
PYTHONPATH=/usr/lib/spark/python/lib/py4j-0.10.4-src.zip
export PYTHONPATH=$SPARK_HOME/python:$PYTHONPATH
export PATH=$PATH:$SBT_HOME/bin:$SPARK_HOME/bin:$SPARK_HOME/sbin
export PATH=$PATH:/home/user1/course/research_methods/spin/Spin/Src6.4.6
export PYSPARK=/usr/lib/spark/bin
export PATH=$PATH:$PYSPARK

export PYSPARK_PYTHON=/home/user1/anaconda3/bin/python3
export PYSPARK_DRIVER_PYTHON=/home/user1/anaconda3/bin/jupyter
export PYSPARK_DRIVER_PYTHON_OPTS="notebook"

# added by Anaconda3 4.2.0 installer
export PATH="/home/user1/anaconda3/bin:$PATH"
export LD_LIBRARY_PATH=/usr/local/hadoop/lib/native/:$LD_LIBRARY_PATH

我在 ~/.jupyter/profile_spark/

中创建了文件“00-pyspark-setup.py”

import os
import sys

spark_home = os.environ.get('SPARK_HOME', None)
sys.path.insert(0, spark_home + "/python")
sys.path.insert(0, os.path.join(spark_home, 'python/lib/py4j-0.8.2.1-src.zip'))

filename = os.path.join(spark_home, 'python/pyspark/shell.py')
exec(compile(open(filename, "rb").read(), filename, 'exec'))

spark_release_file = spark_home + "/RELEASE"

if os.path.exists(spark_release_file) and "Spark 2.1.0" in open(spark_release_file).read():
  pyspark_submit_args = os.environ.get("PYSPARK_SUBMIT_ARGS", "")
  if not "pyspark-shell" in pyspark_submit_args: 
    pyspark_submit_args += " pyspark-shell"
    os.environ["PYSPARK_SUBMIT_ARGS"] = pyspark_submit_args

在此 pyspark installation guide

中推荐

当我运行脚本时，它产生以下输出：

$ ./00-pyspark-setup.py
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

      /_/

Using Python version 3.5.2 (default, Jul  2 2016 17:53:06)
SparkSession available as 'spark'.
$

当我在 jupyter 中打开一个包含以下元数据的 .ipynb 文件时：

 "metadata": {
  "kernelspec": {
   "display_name": "PySpark",
   "language": "python",
   "name": "pyspark"
  },
  "language_info": {
   "codemirror_mode": {
    "name": "ipython",
    "version": 3
   },
   "file_extension": ".py",
   "mimetype": "text/x-python",
   "name": "python",
   "nbconvert_exporter": "python",
   "pygments_lexer": "ipython3"
   "version": "3.5.2"
  }

我收到以下错误：“我找不到与 PySpark 匹配的内核。请 select 一个内核：” 错误信息旁边的一个"kernel"下拉列表只有下面两个选项"Python [conda root]"和"Python [default]"。没有 pyspark 选项。

任何人都可以建议我需要修改什么才能使 pyspark 可用吗？

谢谢

Answer 1

.bashrc -> py4j-0.10.4-src.zip

和

00-pyspark-setup.py -> py4j-0.8.2.1-src.zip

使用不同的 py4j
