I've written a regular expression EvalFunc similar to ExtractAll except
this is called FindAll. It returns a tuple of all strings found that
match the given pattern. The syntax looks like this:
A = FOREACH raw_data GENERATE FindAll(field_str, '[^/]+') AS a_tuple;
I dumped some return tuples which look something like this:
I'm trying to get the size of the tuple so I can filter out certain
entries. If I simply do:
B = FOREACH A GENERATE SIZE(a_tuple);
I always get a size of 1. I thought maybe this was due to the
surrounding bag so I tried to FLATTEN(FindAll(...)). Now I'm getting an
error from SIZE saying it can't convert a string to a DataBag.
Any idea what's going on here?
