火花槽流漏包？

Question

我尝试执行flume流式处理的示例，但无法使我的jars文件正常工作： 在这里 https://github.com/spark-packages/dstream-flume/blob/master/examples/src/main/python/streaming/flume_wordcount.py 他们指出

bin/spark-submit --jars \
      external/flume-assembly/target/scala-*/spark-streaming-flume-assembly-*.jar 

我不知道这个“外部”目录是什么？在

在我的spark（1.6.0）lib中，我放了几个jar（我尝试了1.6.0和1.6.0）：

^{pr2}$

然后我做一个：

    $ ./bin/pyspark --master ip:7077 --total-executor-cores 1 --packages com.databricks:spark-csv_2.10:1.4.0 
--jars /Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib/spark-streaming-flume-sink_2.10-1.6.0.jar 
--jars /Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib/spark-streaming-flume_2.10-1.6.0.jar 
--jars /Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib/spark-streaming-flume-assembly_2.10-1.6.0.jar 

python笔记本服务器启动，但是当我请求一个storm对象时：

from pyspark.streaming.flume import FlumeUtils
from pyspark           import SparkContext
from pyspark           import SparkConf
from pyspark.streaming import StreamingContext
try    : sc.stop()
except : pass
try    : ssc.stop()
except : pass
conf = SparkConf()
conf.setAppName("Streaming Flume")
conf.set("spark.executor.memory","1g")
conf.set("spark.driver.memory","1g")
conf.set("spark.cores.max","5")
conf.set("spark.driver.extraClassPath", "/Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib/")
conf.set("spark.executor.extraClassPath", "/Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib/")
sc  = SparkContext(conf=conf)
ssc = StreamingContext(sc, 10)
FlumeUtils.createStream(ssc, "localhost", "4949")

它失败了：

________________________________________________________________________________________________

  Spark Streaming's Flume libraries not found in class path. Try one of the following.

  1. Include the Flume library and its dependencies with in the
     spark-submit command as

     $ bin/spark-submit --packages org.apache.spark:spark-streaming-flume:1.6.0 ...

  2. Download the JAR of the artifact from Maven Central http://search.maven.org/,
     Group Id = org.apache.spark, Artifact Id = spark-streaming-flume-assembly, Version = 1.6.0.
     Then, include the jar in the spark-submit command as

     $ bin/spark-submit --jars <spark-streaming-flume-assembly.jar> ...

我试着补充

--packages org.apache.spark:spark-streaming-flume-sink.1.6.0

在我的spark提交的最后，我得到了另一个问题：

我从没用过pom.xml文件-也许我应该？在
