How to give multiple directories as input ?

[๏̯͡๏]

I have this piece

sc.newAPIHadoopFile[AvroKey[GenericRecord], NullWritable,
AvroKeyInputFormat[GenericRecord]](
"/a/b/c/d/exptsession/2015/05/22/out-r-*.avro")

that takes ("/a/b/c/d/exptsession/2015/05/22/out-r-*.avro") this as input.

I want to give a second directory as input but this is a invalid syntax


that takes ("/a/b/c/d/exptsession/2015/05/*22*/out-r-*.avro",
"/a/b/c/d/exptsession/2015/05/*21*/out-r-*.avro")

OR

("/a/b/c/d/exptsession/2015/05/*22*/out-r-*.avro,
/a/b/c/d/exptsession/2015/05/*21*/out-r-*.avro")


Please suggest.
