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: 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? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
