我已经关注本手册在我的 Ubuntu 16.04 上运行 spark。我已经下载了 Spark 2.3、Java 9 和 Scala 2.12.5。
在我的/.bashrc中：
export JAVA_HOME=/usr/local/java/jdk-9.0.1
export SPARK_HOME=/usr/bin/spark
export PATH=$PATH:SPARK_HOME/bin
export PATH=$PATH:SPARK_HOME/sbin
export SBT_HOME=/usr/bin/sbt
export PATH=$PATH:$SBT_HOME/bin
在我的spark-env.sh中：
JAVA_HOME=/usr/local/java/jdk-9.0.1
SPARK_MASTER_IP=10.1.20.241
SPARK_WORKER_MEMORY=4g
在文件末尾。
但是当我运行时./spark-shell出现此错误：
