я пытаюсь выполнить пример водопропускной потоковым, но не может иметь мои банки файлы работать: Здесь https://github.com/spark-packages/dstream-flume/blob/master/examples/src/main/python/streaming/flume_wordcount.py они указывают наПоток потокового света - недостающие пакеты?
bin/spark-submit --jars \
external/flume-assembly/target/scala-*/spark-streaming-flume-assembly-*.jar
Я понятия не имею, что это за «внешний» реж?
На моей искры (1.6.0) Lib я положил несколько банок (я пробовал оба 1.6.0 и 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
Тогда я делаю:
$ ./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
сервер ноутбуков питон выстреливает вверх, но потом, когда я прошу штормовой объекта:
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")
он терпит неудачу:
________________________________________________________________________________________________
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> ...

Я пытался добавить
--packages org.apache.spark:spark-streaming-flume-sink.1.6.0
в конце моей искровым представить, но я получаю еще один вопрос:

Я никогда не использовал pom.xml - может быть, я должен ?
