使用Ibis Python将数据插入Impala表

Question

我正在尝试将df插入ibis创建的impala表中。我在远程内核上运行这个，在windows10机器上使用spyder3.2.4，在运行CentOS的边缘节点机器上使用python3.6.2。在

我得到以下错误：

由于hadoop系统的结构和安全性，出现错误。Ibis软件包尝试分别在Ibis tmp和tmp/Ibis/中创建临时数据库和临时hdfs位置。因为在我们的系统中，默认位置不向除根/系统管理员以外的任何用户开放。。。从/tmp/ibis/向实际数据库获取数据时，insert命令出错（仍不清楚，但可能是通过\uu ibis_tmp dbase获得的）。一旦我们编辑了配置_初始py将ibis包的文件保存到允许的临时位置/db。它就像一个符咒。在
