Avro input format available on Giraph?

Hello,

I just wonder does Giraph have an Avro input format reader, which can read
avro input files? If not, could someone let me know where I can get
started? For example, which input format class that I should extend from.
Thanks in advance for your help.

Regards,
Chuan L.

Hello Avery,

Thanks for your input. I noticed the JsonBase64VertexInputFormat class and
plan to mimic its structure to write my own AvroVertexInputFormat. If there
is any questions, I'll send emails to you or user mail list for help.
Again, thank you much for the help.

Not that I know of.  Since it is similar to JSON, you might want to take 
a look at JsonBase64VertexInputFormat as an example for Avro.  Should be 
fairly similar in structure.  Of course, it would be great if you can 
contribute it back to Giraph when you're done. =)
