我在我的Mac上安装了火花，当我在终端中运行spark-submit作业或者使用spark-shell时，一切正常。我还安装了Zeppelin，但是当我尝试在Zeppelin笔记本中运行一个简单的sc时，我收到以下错误。

版本： - 齐柏林飞艇：0.8.0 - 斯卡拉：2.12.8 - Spark：2.3.2 - Java：11.0.2
我在zeppelin-env.sh中包含的3件事： - 导出PYTHONPATH = / usr / bin / python - 导出SPARK_HOME = / usr / local / Cellar / apache-spark / 2.3.2 / libexec - 导出HADOOP_CONF_DIR = / usr / local / bin / hadoop
有谁知道这里可能缺少什么？
如果您的火花回家路径正确，请检查。还可以尝试在Zeppelin Web控制台上将spark解释器设置为本地
检查您的JAVA_HOME是否已设置。
