Subject [jira] [Commented] (HDFS-11010) Update to Protobuf 3 in trunk
Date Fri, 21 Oct 2016 23:32:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15596678#comment-15596678

Andrew Wang commented on HDFS-11010:

bq. I am expecting that our clients will have to move to using new DFSclient since we have
broken so many of those classes already.

[~anu] could you give me some pointers to these breakages between Hadoop 2 and 3? I diffed
the .proto files before alpha1, and only saw one issue (which we fixed, and wasn't client-side).
If there are incompatible wire changes, it's at the very least worth re-examining them.
