Cassandra COPY从命令挂起

Question

我有一个csv文件，我试图将其复制到Cassandra表中。 copy命令能够将csv文件中的数据插入表中。但命令不会在结束时终止。相反，它被卡住了。我必须使用键盘 Ctrl + c 来杀死它。

我想知道，我做错了什么!!

步骤如下： CREATE TABLE IF NOT EXISTS test.things (id uuid PRIMARY KEY, orders text,variable_name text,dataset text,code_list text, definition text, extended text);

cqlsh:test> COPY test.things FROM 'test.csv' WITH DELIMITER=',' AND HEADER=TRUE;

Using 3 child processes
Starting copy of test.things with columns `[id, code_list, dataset, definition, extended, orders, variable_name].;

^C  --- I kill it here after it stuck for a pretty long time
