部署暂时先用默认配置，我们来看看如何提交计算程序到spark上面。
拿官方的Python的测试程序搞一下。
qpzhang@qpzhangdeMac-mini:~/project/spark-1.3.0-bin-hadoop2.4 $cat examples/SimpleApp.py """SimpleApp.py""" from pyspark import SparkContext logFile = "./README.md" # Should be some file on your system sc = SparkContext("local", "Simple App") logData = sc.textFile(logFile).cache() numAs = logData.filter(lambda s: 'a' in s).count() numBs = logData.filter(lambda s: 'b' in s).count() print "Lines with a: %i, lines with b: %i" % (numAs, numBs)
执行结果如下：

这里我起了两个worker，但是只是从运行日志看，没有看到分布式的影子。
强制加上 --deploy-mode cluster 参数，发现Python不支持
qpzhang@qpzhangdeMac-mini:~/project/spark-1.3.0-bin-hadoop2.4 $./bin/spark-submit --master spark://qpzhangdeMac-mini.local:7077 --deploy-mode cluster ./examples/SimpleApp.py Spark assembly has been built with Hive, including Datanucleus jars on classpath Error: Cluster deploy mode is currently not supported for python applications on standalone clusters. Run with --help for usage help or --verbose for debug output Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
换个java的来试试。
这里用的是 https://github.com/databricks/learning-spark/tree/master/mini-complete-example 里面的java word count 的例子。

这里的原因是因为，执行jar包的路径和提交的路径是不一样的。从日志可以看到执行任务的路径：file:/Users/qpzhang/project/spark-1.3.0-bin-hadoop2.4/work/driver-20150325174458-0000/
到这里又不得不提分布式计算的原理了，master把可执行程序（jar包，so等），分发到各个worker（从spark的日志揣测，driver是启动了一个httpserver，供slaver来下载）。
这样我们把输入的文件换成绝对路径就可以了
