NamespaceInfo PB translation drops build version
------------------------------------------------
Key: HDFS-3202
URL: https://issues.apache.org/jira/browse/HDFS-3202
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 2.0.0
Reporter: Aaron T. Myers
The PBHelper#convert(NamespaceInfoProto) function doesn't pass the build
version from the NamespaceInfoProto to the created NamespaceInfo object.
Instead, the NamespaceInfo constructor gets the build version using the static
function Storage#getBuildVersion. DNs also use this static function to
determine their own build version. This means that the check the DN does to
compare its own build version to that of the NN always passes, regardless of
what build version exists on the NN.
