林星火1.3.1(在Ubuntu 14.04)stand alone,SBT 0.13.10,並試圖執行以下腳本:星火之間不同的行爲火花提交和火花外殼
package co.some.sheker
import java.sql.Date
import org.apache.spark.{SparkContext, SparkConf}
import SparkContext._
import org.apache.spark.sql.{Row, SQLContext}
import com.datastax.spark.connector._
import java.sql._
import org.apache.spark.sql._
import org.apache.spark.sql.cassandra.CassandraSQLContext
import java.io.PushbackReader
import java.lang.{ StringBuilder => JavaStringBuilder }
import java.io.StringReader
import com.datastax.spark.connector.cql.CassandraConnector
import org.joda.time.{DateTimeConstants}
case class TableKey(key1: String, key2: String)
object myclass{
def main(args: scala.Array[String]) {
val conf = ...
val sc = new SparkContext(conf)
val sqlContext = new SQLContext(sc)
val csc = new CassandraSQLContext(sc)
val data_x = csc.sql("select distinct key1, key2 from keyspace.table where key1 = 'sheker'").map(row => (row(0).toString, row(1).toString))
println("Done cross mapping")
val snapshotsFiltered = data_x.map(x => TableKey(x._1,x._2)).joinWithCassandraTable("keyspace", "table")
println("Done join")
val jsons = snapshotsFiltered.map(_._2.getString("json"))
...
sc.stop()
println("Done.")
}
}
使用:
/home/user/spark-1.3.1/bin/spark-submit --master spark://1.1.1.1:7077 --driver-class-path /home/user/spark-cassandra-connector-java-assembly-1.3.1-FAT.jar --properties-file prop.conf --class "myclass" "myjar.jar"
的prop.conf文件是:
spark.cassandra.connection.host myhost
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.eventLog.enabled true
spark.eventLog.dir /var/tmp/eventLog
spark.executor.extraClassPath /home/ubuntu/spark-cassandra-connector-java-assembly-1.3.1-FAT.jar
我得到這個例外:
Done cross mapping

Done Sending Signal aggregation job to Spark
和奇怪的部分是,當我試圖在外殼的運行從腳本 - 命令做工精細。即時通訊使用:
/home/user/spark-1.3.1/bin/spark-shell --master spark://1.1.1.1:7077 --driver-class-path /home/ubuntu/spark-cassandra-connector-java-assembly-1.3.1-FAT.jar --properties-file prop.conf
的Build.scala文件:
import sbt._
import Keys._
import sbtassembly.Plugin._
import AssemblyKeys._
object AggregationsBuild extends Build {
lazy val buildSettings = Defaults.defaultSettings ++ Seq(
version := "1.0.0",
organization := "co.sheker",
scalaVersion := "2.10.4"
)
lazy val app = Project(
"geo-aggregations",
file("."),
settings = buildSettings ++ assemblySettings ++ Seq(
parallelExecution in Test := false,
libraryDependencies ++= Seq(
"com.datastax.spark" %% "spark-cassandra-connector" % "1.2.1",
// spark will already be on classpath when using spark-submit.
// marked as provided, so that it isn't included in assembly.

),
resolvers += "conjars.org" at "http://conjars.org/repo",

)
)
}
有什麼不對?爲什麼它在提交時失敗,但不在shell中?
你是如何創建提交的jar?你需要做一個裝配,而不是一個包裝。 – Reactormonk
@Reactormonk - 是的,我做「sbt程序集」給我的「myjar.jar」文件 – Rada
你說你使用的是Spark 1.3,但你的版本包含Spark 1.2.1的依賴關係。你檢查了嗎?我相信你的火花驅動程序的版本與你應用程序中的版本不同,導致你得到的錯誤。 – eliasah
