> In our production env, we generate avro files to track some user behavior
> events. Every hour, we will have several avro files created. And daily, we
> will run MR to do analysis, when using AvroKeyValueInputFormat, a lot of
> small mappers started due to we have small avro files.
> A combine file inputformat will be very helpful for such case.
> Hadoop already provided some implementation for sequencefile and text file.
> This Jira is propose a CombineAvroKeyValueFileInputFormat class to implement
> the same for avro keyvalue files.
