Hadoop PIG拉丁语中的连接条件 SQL 猪

现在我需要使用上述sql条件连接这两个表。 如何使用连接条件在PIG中实现上述逻辑？

尝试以下方法：

A = LOAD 'mydata1' AS (x: int, y: datetime);
B = LOAD 'mydata2' AS (a: int, b: datetime);

由于这是不可能的，请尝试将try‘CROSS’与‘FILTER’结合使用

A = LOAD 'mydata1' AS (x: int, y: datetime);
B = LOAD 'mydata2' AS (a: int, b: datetime);  

A = LOAD 'mydata1' AS (x: int, y: datetime);  
B = LOAD 'mydata2' AS (a: int, b: datetime); 
C = JOIN A BY x, B BY a;
D = FILTER C BY ToUnixTime(y) >= ToUnixTime(b);
DUMP D;
