apache-spark - ./spark-shell 没有正确启动(spark1.6.1-bin.hadoop2.6 版本)

Question

我安装了这个 spark 版本:spark-1.6.1-bin-hadoop2.6.tgz。

现在，当我用 ./spark-shell 开始 Spark 时命令我遇到了这个问题(它显示了很多错误行，所以我只放了一些看起来很重要的)

我尝试了一些配置来解决这个问题，我在关于值 sqlContext not found 问题的其他问题中搜索，例如:

/etc/hosts 文件:

127.0.0.1  hadoophost localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    10.2.0.15 hadoophost

echo $HOSTNAME返回:

主机

.bashrc 文件包含:

export SPARK_LOCAL_IP=127.0.0.1

但是不起作用，您能否提供一些帮助以尝试了解为什么 Spark 无法正确启动？

显然您没有权限在该目录中写入，我建议您运行 ./spark-shell在您的 HOME (您可能希望将该命令添加到您的 PATH )，或者您的用户可以访问和写入的任何其他目录中。
