Question

我尝试执行水槽流的示例，但不能让我的jar文件工作：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

我不知道这是什么＆＃34;外部＆＃34; dir？

在我的spark（1.6.0）lib上我放了几个罐子（我试过1.6.0和1.6.0）：

$ pwd
/Users/romain/Informatique/zoo/spark-1.6.0-bin-hadoop2.4/lib
$ ls *flume*
spark-streaming-flume-assembly_2.10-1.6.0.jar   
spark-streaming-flume-assembly_2.10-1.6.2.jar   

spark-streaming-flume-sink_2.10-1.6.2.jar
spark-streaming-flume-sink_2.10-1.6.0.jar

spark-streaming-flume_2.10-1.6.0.jar
spark-streaming-flume_2.10-1.6.2.jar

然后我做了一个：

    $ ./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，但是当我要求风暴对象时：

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")

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> ...

我试图添加

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

在我的火花提交结束时，但我得到了另一个问题：

我从未使用过pom.xml - 也许我应该这样做？
