我正在使用ubuntu来设置独立的火花。但是当我使用预制火花时，它未能找到slf4j包。
./spark-1.4.1-bin-without-hadoop/sbin/start-master.sh
Spark Command: /usr/lib/jvm/java-7-oracle//bin/java -cp /root/spark-1.4.1-bin-without-hadoop/sbin/../conf/:/root/spark-1.4.1-bin-without-hadoop/lib/spark-assembly-1.4.1-hadoop2.2.0.jar -Xms512m -Xmx512m -XX:MaxPermSize=256m org.apache.spark.deploy.master.Master --ip localhost --port 7077 --webui-port 8080

对不起，我不应该使用spark-1.4.1-bin-without-hadoop，当我下载spark-1.4.1-bin-hadoop2.6时它会起作用。这可能是我使用的问题，而不是Spark。
