Pyspark --py文件不起作用

我使用此文件建议http://spark.apache.org/docs/1.1.1/submitting-applications.html

spsark版本1.1.0

./spark/bin/spark-submit --py-files /home/hadoop/loganalysis/parser-src.zip \
/home/hadoop/loganalysis/ship-test.py 

和代码中的conf:

conf = (SparkConf()
        .setMaster("yarn-client")
        .setAppName("LogAnalysis")
        .set("spark.executor.memory", "1g")
        .set("spark.executor.cores", "4")
        .set("spark.executor.num", "2")
        .set("spark.driver.memory", "4g")
        .set("spark.kryoserializer.buffer.mb", "128"))

和slave节点抱怨ImportError

14/12/25 05:09:53 WARN scheduler.TaskSetManager: Lost task 0.0 in stage 0.0 (TID 0, ip-172-31-10-8.cn-north-1.compute.internal): org.apache.spark.api.python.PythonException: Traceback (most recent call last):

  File "/home/hadoop/spark/python/pyspark/serializers.py", line 150, in _read_with_length

和parser-src.zip在本地测试.

[hadoop@ip-172-31-10-231 ~]$ python
Python 2.7.8 (default, Nov  3 2014, 10:17:30)

>>> import sys
>>> sys.path.insert(1, '/home/hadoop/loganalysis/parser-src.zip')
>>> from parser import parser
>>> parser.parse

>>> 

我正在尝试获取有关远程工作人员的信息.看看它是否复制了文件.sys.path看起来是什么......这很棘手.

更新:我用这个发现zip文件已被删除.和sys.path已设置.仍导入获取错误.

data = list(range(4))
disdata = sc.parallelize(data)
result = disdata.map(lambda x: "sys.path:  {0}\nDIR: {1}   \n FILES: {2} \n parser: {3}".format(sys.path, os.getcwd(), os.listdir('.'), str(parser)))
result.collect()
print(result.take(4))

我似乎不得不深入挖掘cloudpickle.这意味着我需要了解cloudpickle是如何工作的并且首先失败.

: An error occurred while calling o40.collect.

更新:

有人在火花0.8遇到同样的问题 http://apache-spark-user-list.1001560.n3.nabble.com/pyspark-Importing-other-py-files-in-PYTHONPATH-td2301.html

但他把他的lib放在python dist-packages和导入作品中.我试过但仍然导致导入错误.

更新:

OH.gush ..我认为问题是由于不了解zip文件和python导入行为引起的.我将parser.py传递给--py文件,它有效,抱怨另一个依赖.和zip只有.py文件[不包括.pyc]似乎也有效.

但我不太明白为什么.
