無法啟動spark-shell

Question

我正在使用Spark 1.4.1。 我可以毫無問題地使用spark-submit。 但是當我跑~/spark/bin/spark-shell

我收到了以下錯誤，我已經配置了SPARK_HOME和JAVA_HOME 。 但是，Spark 1.2沒關系

Answer 1

我遇到了運行spark的同樣問題，但我發現沒有正確配置scala是我的錯。 確保安裝了Java，Scala和sbt並構建了Spark：

編輯你的.bashrc文件vim .bashrc

設置你的env變量：

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

來源您的設置。 的.bashrc

檢查scala scala -version

確保repl啟動scala

如果你的擊退開始嘗試再次開始你的火花殼。 ./path/to/spark/bin/spark-shell

你應該得到火花repl

Answer 2

你可以嘗試跑步

spark-shell -usejavacp

它對我不起作用，但它在Spark Issue 18778的描述中確實有效。

Answer 3

你安裝了scala和sbt嗎？
日志說它沒有找到主類。
