Question

我正在使用Spark 1.4.1。我可以毫无问题地使用spark-submit。但是当我跑~/spark/bin/spark-shell

时

我收到了以下错误我已配置SPARK_HOME和JAVA_HOME。但是，Spark 1.2没关系

15/10/08 02:40:30 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

Answer 1

我遇到了运行spark的同样问题，但我发现没有正确配置scala是我的错。确保安装了Java，Scala和sbt并构建了Spark：

编辑.bashrc文件 vim .bashrc

设置你的env变量：

export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export PATH=$JAVA_HOME:$PATH

export SCALA_HOME=/usr/local/src/scala/scala-2.11.5
export PATH=$SCALA_HOME/bin:$PATH

export SPARK_HOME=/usr/local/src/apache/spark.2.0.0/spark
export PATH=$SPARK_HOME/bin:$PATH

获取您的设置。 .bashrc中

检查scala scala -version

确保repl启动阶

如果你的击退开始尝试再次开始你的火花壳。 ./path/to/spark/bin/spark-shell

你应该得到spark repl

Answer 2

您可以尝试运行

fact

它对我不起作用，但它在Spark Issue 18778的描述中对某人有用。

Answer 3

你安装了scala和sbt吗？日志说没找到主要班级。

无法启动spark-shell
