Hadoop：hadoop-2.6.4
Spark：spark-1.6.0-bin-without-hadoop
JAVA_HOME和Hadoop / bin文件夹位于$ PATH
在conf / spark-env.sh中 export SPARK_DIST_CLASSPATH = $（/ hadoop-2.6.4 / bin / hadoop classpath）
当我从Spark（bin / run-example SparkPi）运行示例时，异常如下：

答案 0 :(得分：2)
错误清楚地说，它无法在类路径中找到snappy-java库。 下载并添加到spark lib。 https://github.com/xerial/snappy-java
Snappy用于压缩数据，然后在spark节点之间传输，从源传输到spark。
