我有以下情况:
Cassandra的表:
CREATE TABLE tb_st_test (
id int,
email list<text>,
PRIMARY KEY ((id));
PIG代码:
teste = LOAD 'cql://main/tb_st_test' USING CqlStorage();
testing = FOREACH teste GENERATE $0 as cod, ['emailtest@test.com'] as field:();
insert_test =
FOREACH testing GENERATE
TOTUPLE(
TOTUPLE('id',cod)
),
TOTUPLE(field);
STORE insert_test INTO 'cql://main/tb_st_test?output_query=UPDATE tb_st_test set email %3D%3F' USING CqlStorage();
这里的想法是阅读表tb_st_test,获取键值,并更新字段电子邮件。 但是当我运行脚本时,我收到以下错误:
java.io.IOException: org.apache.thrift.transport.TTransportException

有谁知道它发生了什么?
答案 0 :(得分:0)
insert_test格式错误,因为列表集合格式应该是TOTUPLE(TOUTUPLE('some email','email2'))。检查https://issues.apache.org/jira/browse/CASSANDRA-5867
