Question

我正在尝试过滤位置变量。

X = FILTER C BY($14 matches '.*USD.*');
STORE X into '$output' using PigStorage(',');

以上陈述不起作用，但如果我尝试输出$ 14

E = FOREACH C GENERATE FLATTEN($14);
STORE C into '$output' using PigStorage(',');

工作正常

Answer 1

在'BY'和'（'

之间添加一个空格

    X = FILTER C BY (FLATTEN($14) matches '.*USD.*');
    STORE X into '$output' using PigStorage(',');

Answer 2

这对我来说很有意义：

A = LOAD 'StackFile.txt'  using PigStorage(',');
B = FILTER A BY ($14 matches '.*USD.*');
DUMP B;
