Question

我是Cassandra世界的新手，并试图将一个csv数据文件导入我在Windows 7上新创建的cassandra服务器用于学习目的，我正在关注数据同步在线教程，并且卡在了上面 https://academy.datastax.com/courses/installing-configuring-and-manipulating-keyspace/copying-external-data-tables-development

当我尝试复制csv文件时，它会给我错误

cqlsh> use musicdb
   ... ;
cqlsh:musicdb> copy album(title,year,performer,genre,tracks)
           ... from 'album.csv'
           ... with header = true;

Error starting import process:

Can't pickle <type 'thread.lock'>: it's not found as thread.lock
can only join a started process
cqlsh:musicdb> Traceback (most recent call last):
  File "<string>", line 1, in <module>

    file, path_name, etc = imp.find_module(main_name, dirs)
ImportError: No module named cqlsh

cqlsh:musicdb>

我的album.csv文件与cqlsh.exe位于同一文件夹中

cqlsh：复制命令错误ImportError：没有名为cqlsh的模块
