Subject [jira] [Commented] (HDFS-3809) Make BKJM use protobufs for all serialization with ZK
Date Tue, 30 Oct 2012 19:52:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487160#comment-13487160

Uma Maheswara Rao G commented on HDFS-3809:
-------------------------------------------

ok, Adding '+package hadoop.hdfs;' fixed the problem. I will commit new patch.
Generally we will not keep changes.txt in patches. do you mind removing it. For me it is fine
to commit above patch. Asking just to keep patches in JIRA consistently.

> HDFS uses protobufs for serialization in many places. Protobufs allow fields to be added
without breaking bc or requiring new parsing code to be written. For this reason, we should
use them in BKJM also.
