Spark with Flume (配置/类路径？)

Question

我正在尝试让Spark与Flume一起工作，flume配置如下：

#Declare
log.sources = src
log.sinks = spark
log.channels = chs

#Define Source

log.sources.src.type = exec
log.sources.src.command = sh /home/user/shell/flume.sh

#Define Sink
log.sinks.spark.type = org.apache.spark.streaming.flume.sink.SparkSink
log.sinks.spark.hostname = localhost
log.sinks.spark.port = 9999
log.sinks.spark.channel = chs

#Define Channels

log.channels.chs.type = memory

#Tie Source and Sink to Channel

log.sinks.snk.channel = chs
log.sources.src.channels = chs

$ ls -lrt $FLUME_CLASSPATH

$flume-ng -n -f simplelogger.conf -n日志

        ... 14 more

在pwd中还有一个plugins.d文件夹(我在那里有flume conf)

plugins.d/：

plugins.d/spark：

plugins.d/spark/lib：

-rw-r--r-- 1 rgopalk rgopalk 82325 11-7 19:31 spark-streaming flume-sink_2.11-1.2.0.jar

有什么建议吗？

PS: flume_classpath中的spark-streaming jar和scala-library jar的多个版本没有任何区别。单版本错误相同

我将上面列出的所有jar文件复制到{FLUME_INSTALLATTION_DIR/libs。我还复制了{SPARK_HOME}/lib/spark-assembly到{FLUME_INSTALLATTION_DIR/libs，它开始工作了
