Philipp,
I would say that it is a bug. I ran into the same problem some time
ago. Essentially, AvroStorage does not recognize globs and does not
recognize commas, both of which
are supported by hadoop's FileInputFormat. I ended up patching
AvroStorage to make it compatible with hadoop's semantics of input
paths. I haven't submitted a patch though.
If there is some interest, I'd be more than glad to submit it.
Bets,
stan

Dear Pig users,
I tried to load several files with AvroStorage by using a comma separated
list. The statement I used is:
test_data= LOAD 'repo_1/part-r-00000.avro,repo_2/part-r-00000.avro' USING
org.apache.pig.piggybank.storage.avro.AvroStorage();
Pig states that no input paths were specified in job. Please see the
stacktrace below.
I tried pig version0.8.1-cdh3u2 and 0.9.1.
Does anyone observe the same behavior? Is it a bug or a feature?
Thanks, Philipp
