hadoop - Spark : Execute python script with Spark based on Hadoop Multinode

转载作者：可可西里更新时间：2023-11-01 16:37:23

我正在寻找基于 Hadoop Multinodes 的 Spark 使用，我对我的集群模式 pythonic 脚本有疑问。

我的配置:

我进入了我的 Hadoop 集群:

1 个名称节点(主节点)
2 个数据节点(从节点)

所以我想在 Python 中执行我的脚本以使用这个集群。我知道 Spark 可以用作独立模式，但我想使用我的节点。

我的 python 脚本:

这是一个非常简单的脚本，可以用来计算文本中的字数。

import sys
from pyspark import SparkContext

sc = SparkContext()
lines = sc.textFile(sys.argv[1])
words = lines.flatMap(lambda line: line.split(' '))
words_with_1 = words.map(lambda word: (word, 1))
word_counts = words_with_1.reduceByKey(lambda count1, count2: count1 + count2)
result = word_counts.collect()

for (word, count) in result:
    print word.encode("utf8"), count

我的 Spark 命令:

为了使用 Spark，我这样做:

time ./bin/spark-submit --master spark://master:7077 /home/hduser/count.py /data.txt

但是，这个命令可以在独立模式下执行 Spark 对吗？我如何使用我的 Hadoop 集群(例如 yarn)执行 Spark 并在我的集群上进行并行和分布式计算？

我试过了:

time ./bin/spark-submit --master yarn /home/hduser/count.py /data.txt

我遇到了问题:

当我想将我的集群与 Spark 一起使用时，我总是遇到FAILED

终于试过了:

time ./bin/spark-submit --master yarn --deploy-mode cluster /home/hduser/count.py /data.txt

但我又遇到了一次问题。

我有什么不明白？我对大数据很陌生，所以有可能:/编辑:

最佳答案

对我来说，这个 spark 提交在所有 spark 节点上运行 python:

spark-submit --master yarn 
             --deploy-mode cluster 
             --num-executors 1 
             --driver-memory 2g 
             --executor-memory 1g 
             --executor-cores 1 
             hdfs://<host>:<port>/home/hduser/count.py /data.txt

Spark 环境需要扩展:导出 PYSPARK_PYTHON=/opt/bin/python

此外，py 文件需要位于 hdfs 上，以便集群中的所有 spark 节点都可以读取它。 spark 用户需要可以访问 py 文件。
