stack updated HBASE-4300:
-------------------------
Attachment: 4300.txt
Add new static parseServerName method to ServerName. It tests the passed
String to see if it matches the ServerName pattern, if not, it tries to treat
the string as "<hostname> ':' <port>". Replaced all places where we get raw
'new ServerName' instances that take raw zk bytes with this new parseServerName
method.
One day should protobuf/json it all. Would need to allow for the binary
preamble all data has since we added in RecoverableZookeeper.
