我试图在pig中运行一个test pig脚本,从datasax企业的cassandra加载数据,但是我得到了一个错误。让我展示整个场景:
cassandra架构:创建keyspace libdata,replication={'class':'simplestrategy','replication\u factor':1};
创建表libout(“stabr”文本、“fscskey”文本、“fscs\ seq”文本、“libid”文本、“libname”文本、“address”文本、“city”文本、“zip”文本、“zip4”文本、“cnty”文本、“phone”文本、“c\ u out\ ty”文本、“c\ msa”文本、“sq\ ft”文本、“l\ u num\ u bm”int、“f\ u bkmob”文本、“hours”int、“f\ u hours”文本、“wks\ u open”int、“f\ u wksopn”文本、“yr\ u sub”int,“statstru”int、“statname”int、“statadr”int、“longitud”float、“latitude”float、“fipsst”int、“fipsco”int、“fipsplac”int、“cntypop”int、“locale”text、“centract”float、“cenblock”int、“cdcode”text、“mat\cent”text、“mat\u type”int、“cbsa”int、“microf”text、主键(“fscskey”、“fscs\ seq”);
cqlsh:libdata>创建表libsqft(year int,state text,sqft bigint,主键(year,state));第二个表将用于存储从pig到cassandra的数据。
在pig grunt:grunt>libdata=load'cql://libdata/libout'使用cqlstorage();咕噜>转储libdata;
这是我的输出:
