无法使用'来自'的COPY将数据导入Cassandra表/列系列命令。
我们尝试了
cqlsh> copy eqdata from '/home/swiftguy/cassandra/earthquakedata/weather-data-with-uuid.csv';
Bad Request: line 1:298 no viable alternative at input ')'
Aborting import at record #0 (line 1). Previously-inserted values still present.
表格详情
create table earthquakedata(eqtime timestamp,Longitude float, 纬度浮点数,深度浮点数,幅度浮点数,MagType文本,NbStations float,Gapv float,distance float,RMS float,Source text,EventID text,Version text,id uuid,primary key(eqtime,id));
这是我们要导入的csv file
请帮帮我。提前谢谢。

从http://www.datastax.com/documentation/tutorials/gis.zip下载带有地震数据的gis.zip,并将CSV与您正在使用的CSV进行比较。有一个标题和逗号用作分隔符,但基本上不会更改可用的公共数据。在cqlsh中,请记住在COPY命令中调整'path / earthquakes.csv'并使用默认的COPY选项:
CREATE TABLE earthquakes ( datetime text PRIMARY KEY, latitude double, longitude double, depth double, magnitude double, magtype text, nbstations int, gap double, distance double, rms double, source text, eventid int ); COPY earthquakes (datetime, latitude, longitude, depth, magnitude, magtype, nbstations, gap, distance, rms, source, eventid) FROM 'path/earthquakes.csv' WITH HEADER = 'true';
运行Brian的python脚本以添加UUID并调整UUID的表后,运行此命令导入所有行:
cqlsh:mykeyspace> COPY earthquakes (datetime, latitude, longitude, depth, magnitude, magtype, nbstations, gap, distance, rms, source, eventid,newid) FROM '/Users/krishahn/Downloads/gis/out.csv' WITH HEADER = 'true'; 77037 rows imported in 2 minutes and 35.913 seconds.
