pass data into outputSchema method

[John Smith]

Hi there,


is there any way how can I pass filename/string/or any other data/ into
fronted method outputSchema()? There are distributedCaches, UDFcontext but
as far as i understood both work with backed methods i.e exec().


I need to pre-compute some data before the execution of the pig scrip and
use it inside outputSchema(). Basically i need to create/generate
outputSchema() based on the pre-computed data from one of the source
dataset.


Any ideas?


Thanks
