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.
