CCE：BinSedesTuple不能轉換爲String

我試圖處理以下數據：CCE：BinSedesTuple不能轉換爲String

B = FOREACH A GENERATE FLATTEN(vitalStatus); 
DUMB B; 
(value,LIVING) 
(value,LIVING) 
(value,LIVING) 
(value,DECEASED) 
(value,LIVING) 
(value,DECEASED) 
(value,DECEASED) 
(value,LIVING)

但是當我嘗試對其進行過濾（過濾器BY vitalStatus匹配'死者）我在做什麼錯？

我收到以下錯誤：

2013-08-23 08:47:16,290 [Thread-4] WARN org.apache.hadoop.mapred.LocalJobRunner - job_local_0001

什麼是輸出'DESCRIBE乙;'？ – mr2ert

B：{vitalStatus：chararray} – e90jimmy

如果數據來自CqlStorage，cassandra客戶端是豬。 – e90jimmy
