---------------------------------------
Summary: Upgrade Avro dependency to 1.7.7
Key: HADOOP-12527
URL: https://issues.apache.org/jira/browse/HADOOP-12527
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.7.1
Reporter: Jonathan Kelly
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:

Would it be possible to upgrade Hadoop's Avro dependency to 1.7.7 now?
