无法拆分包含单词之间空格和制表符的字符数组字段。帮助我使用 Apache Pig 命令？
Not able to split chararray field containing spaces and tabs between the words. Help me with the command using Apache Pig?

当我执行建议的命令时，它被分成三个字段。
当我执行以下操作时，它没有按预期工作。
A = LOAD 'Sample.txt' USING PigStorage() as (line:chararray);
B = foreach A generate STRSPLIT(line, ' ', 3);
c = foreach B generate ;
split C into buslog if [=11=] matches '.*bus*.', trainlog if [=11=] matches '.*train*.';
注意：- C 的转储将给出以下结果。
THURSDAY -39 3 Pick up a bus - Travel for two hours
FRIDAY -55 8 Pick up a train - Travel for one hour
SUNDAY -55 8 Pick up a train - Travel for one hour
需求：在上面的结果中，我想把train和bus拆分成两个关系，但是没有按预期发生
语法是.*string.*。注意字符串两边都是.*。
split C into buslog if [=10=] matches '.*bus.*', trainlog if [=10=] matches '.*train.*';
