Steve Loughran commented on HADOOP-19164:
-----------------------------------------
* be nice to cut the need for mockito out
* and we should be able to add a test for this in
https://github.com/apache/hadoop-release-support ... something which jsut
tries to issue the command in the unzipped distro dir
and yes "NOTE: You will need protoc 2.5.0 installed." is out. maybe we should
grep the docs for "protobuf"
