Subject [jira] [Commented] (HADOOP-13386) Upgrade Avro to 1.8.x
Date Fri, 26 Apr 2019 10:33:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16826864#comment-16826864

Steve Loughran commented on HADOOP-13386:

# What extra transitive dependencies does this this change?
# Has anyone tested code built with a version of hadoop *before* the upgrade running on a
hadoop cluster with the upgrade?

It's the changes in generated code which is going to break things here, just as with protobuf.
This doesn't mean I don't support the upgrade —I do— but I want to know how incompatible
a change it is.

> Avro 1.8.x makes generated classes serializable which makes them much easier to use with
Spark. It would be great to upgrade Avro to 1.8.x
