matches with regular expression in pig

[Zhen Guo]

Hi all,

In pig, we can do pattern matching with regular expression. For a pattern
like "abc|.*", how to write the regular expression?

I tried the following:

A = FILTER B BY (name matches 'abc\|.*');

but it does not work. I cannot use 'abc|.*' because it will match anything.

Any ideas are appreciated.

Thanks,

Zhen
