无法启动火花壳

Question

我使用的是 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

我收到以下错误 我已经配置了SPARK_HOME 和JAVA_HOME。 但是，Spark 1.2 没问题

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

我在运行 spark 时遇到了同样的问题，但我发现没有正确配置 scala 是我的错。 确保你已经安装了 Java、Scala 和 sbt 并构建了 Spark：

编辑你的 .bashrc 文件 vim .bashrc

设置你的环境变量：

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

检查斯卡拉 scala-版本

确保 repl 启动 斯卡拉

如果您的排斥开始尝试再次启动您的火花外壳。 ./path/to/spark/bin/spark-shell

你应该得到 spark repl

Answer 2

你可以试试跑步

spark-shell -usejavacp

它不适用于我，但它确实适用于 Spark Issue 18778 描述中的某人。

Answer 3

你安装了 scala 和 sbt 吗？
日志说没有找到主类。
