-PigStorage problem for nested structures?
Yang 2012-06-28, 19:48
if I have a field that contains ",", and I add it to a tuple,
then then tuple becomes part of a row in a relation.
I STORE the relation using PigStorage.
so each row is a nested tuple.
then the "," in the content can not be distinguished from the separator
used by pigStorage.
what is the easiest way out of this?
(preprocessing to escape "," ? another more powerful storage format? )
