Scala 必须包括log4J，但它会在apachesparkshell中导致错误。如何避免错误？

由于JAR的复杂性，我必须将其包含在Spark代码中，因此我想寻求帮助，找出在不删除log4j导入的情况下解决此问题的方法

简单代码如下：

    :cp symjar/log4j-1.2.17.jar
import org.apache.spark.rdd._

      val hadoopConf=sc.hadoopConfiguration;
      hadoopConf.set("fs.s3n.impl", "org.apache.hadoop.fs.s3native.NativeS3FileSystem")
      hadoopConf.set("fs.s3n.awsAccessKeyId","AKEY")
      hadoopConf.set("fs.s3n.awsSecretAccessKey","SKEY") 
    val numOfProcessors = 2
    val filePath = "s3n://SOMEFILE.csv"
    var rdd = sc.textFile(filePath, numOfProcessors)
    def doStuff(rdd: RDD[String]): RDD[String] = {rdd}
    doStuff(rdd)

首先，我得到了这个错误：

error: error while loading StorageLevel, class file '/root/spark/lib/spark-assembly-1.3.0-hadoop1.0.4.jar(org/apache/spark/storage/StorageLevel.class)' has location not matching its contents: contains class StorageLevel
error: error while loading Partitioner, class file '/root/spark/lib/spark-assembly-1.3.0-hadoop1.0.4.jar(org/apache/spark/Partitioner.class)' has location not matching its contents: contains class Partitioner
error: error while loading BoundedDouble, class file '/root/spark/lib/spark-assembly-1.3.0-hadoop1.0.4.jar(org/apache/spark/partial/BoundedDouble.class)' has location not matching its contents: contains class BoundedDouble
error: error while loading CompressionCodec, class file '/root/spark/lib/spark-assembly-1.3.0-hadoop1.0.4.jar(org/apache/hadoop/io/compress/CompressionCodec.class)' has location not matching its contents: contains class CompressionCodec

然后，我再次运行此行，错误消失：

var rdd = sc.textFile(filePath, numOfProcessors)

然而，该准则的最终结果是：

error: type mismatch;
 found   : org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.RDD[String]
 required: org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.org.apache.spark.rdd.RDD[String]
              doStuff(rdd)
                      ^

我怎样才能避免从导入中删除log4j而不获得提到的错误？（这很重要，因为我使用的jar大量使用log4j，并且与sparkshell冲突）。

答案不仅仅是使用：cp命令，而是在exportSpark\u SUBMIT\u CLASSPATH=“…/the/path/to/a.jar”

下添加包含…/Spark/conf/Spark-env.sh中的所有内容，如果使用诸如Scala for Eclipse和maven之类的IDE，则将从maven中排除JAR。例如，我想排除OMMNS编解码器（然后将不同版本作为JAR包含到项目中），并在pom.xml中添加了如下更改：
