我有这个猪脚本：

我知道RUB_216列包含整数，但由espace给出： 就像：
;16 ;
;17 ;
..
所以我决定将其转换为chararray。
运行Pig脚本时：
错误0：执行时发生异常（名称：CRE_22002_DATA：新建 每个（false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false， false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false，false， false，false，false，false，false，false，false，false）[袋] -scope-353操作员密钥：scope-353）：org.apache.pig.backend.executionengine.ExecException：错误0： 执行[POUserFunc（名称： POUserFunc（org.apache.pig.builtin.ToDate2ARGS）[datetime]-范围179 操作员密钥：scope-179）子元素：[[]]为空： java.lang.IllegalArgumentException：格式无效：“ RUB_216”
请帮忙吗？
