Spark权限问题：Spark-submit运行报错
Permission denied user=deploy
这个问题是权限问题，只需要修改一下hdfs路径的权限就好了
原本的权限
# hdfs dfs -ls /user/spark/ drwxr-xr-x - spark spark /user/spark/applicationHistory drwxr-xr-x - spark spark /user/spark/spark2ApplicationHistory
修改成如下权限就可以了
# hdfs dfs -ls /user/spark/ drwxr-xr-x - spark spark /user/spark/applicationHistory drwxr-xr-x - deploy spark /user/spark/spark2ApplicationHistory
