    No, I don't think it's necessary. It just seems like it'd be good to do at some point

>             Project: Hadoop Common
>          Issue Type: Improvement

>    Affects Versions: 2.7.1

> Hadoop has depended upon Avro 1.7.4 for a couple of years now (see HADOOP-9672), but
Apache Spark depends upon what is currently the latest version of Avro (1.7.7).
> This can cause issues if Spark is configured to include the full Hadoop classpath, as
the classpath would then contain both Avro 1.7.4 and 1.7.7, with the 1.7.4 classes possibly
winning depending on ordering. Here is an example of this issue: http://stackoverflow.com/questions/33159254/avro-error-on-aws-emr/33403111#33403111
> Would it be possible to upgrade Hadoop's Avro dependency to 1.7.7 now?
