./spark-shell无法正常启动(spark1.6.1-bin.hadoop2.6版本)

Question

我安装了这个火花版:spark-1.6.1-bin-hadoop2.6.tgz.

现在当我用./spark-shell命令启动spark时我得到了这个问题(它显示了很多错误行,所以我只是把一些看起来很重要)

        scala> 

我尝试了一些配置来解决这个问题,我在其他关于sqlContext值找不到问题的问题中搜索,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 收益:

hadoophost

.bashrc文件包含:

export SPARK_LOCAL_IP=127.0.0.1

但是不行,你可以帮助尝试理解为什么火花没有正确启动？

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

这也可能与您的笔记本和Spark一起使用
