问题描述

我收到以下错误，当我尝试调用
我使用Python客户端的火花。

I get the following error when I try to callI use python client for the spark.

lines = sc.textFile(hdfs://...)
lines.take(10)

我怀疑是火花和Hadoop版本可能不兼容。以下是Hadoop的版本的结果：
    Hadoop的2.5.2
    颠覆 -r cc72e9b000545b86b75a61f4835eb86d57bfafc0
    詹金斯在2014-11-14T23编译：45Z
    与protoc 2.5.0编译
    从校验df7537a4faa4658983d397abf4514320源
该命令使用/etc/hadoop-2.5.2/share/hadoop/common/hadoop-common-2.5.2.jar运行

I suspect that spark and hadoop versions might not be compatible. Here are the result of hadoop version: Hadoop 2.5.2 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r cc72e9b000545b86b75a61f4835eb86d57bfafc0 Compiled by jenkins on 2014-11-14T23:45Z Compiled with protoc 2.5.0 From source with checksum df7537a4faa4658983d397abf4514320This command was run using /etc/hadoop-2.5.2/share/hadoop/common/hadoop-common-2.5.2.jar

我也有火花1.3.1。

I also have spark 1.3.1.

我一直在寻找这个问题，有人称它为protobuffer的版本，但我不是很熟悉如何正确设置它。任何想法？

I have been searching for the problem, some people refer to the version of protobuffer but I am not very familiar how to set it up correctly. Any idea?
