Improve TransferFsImage
-----------------------
Key: HADOOP-5506
URL: https://issues.apache.org/jira/browse/HADOOP-5506
Project: Hadoop Core
Issue Type: Improvement
Components: dfs
Affects Versions: 0.17.0
Reporter: Konstantin Shvachko
{{TransferFsImage}} transfers name-node image and edits files during checkpoint
process.
# {{TransferFsImage}} should *always* pass and verify CheckpointSignature. Now
we send it only when image is uploaded back to name-node.
# {{getFileClient()}} should use {{Collection<File>}} rather than {{File[]}} as
the third parameter.
# Rather than sending port and address separately {{"&port=" + port +
"&machine=" + addr}} it should send the entire address at once.
