Examples of org.apache.hadoop.hbase.ServerName

org.apache.hadoop.hbase.ServerName
Instance of an HBase ServerName. A server name is used uniquely identifying a server instance in a cluster and is made of the combination of hostname, port, and startcode. The startcode distingushes restarted servers on same hostname and port (startcode is usually timestamp of server startup). The {@link #toString()} format of ServerName is safe to use in the filesystem and as znode nameup in ZooKeeper. Its format is: <hostname> ' {@link #SERVERNAME_SEPARATOR}' <port> ' {@link #SERVERNAME_SEPARATOR}' <startcode>. For example, if hostname is www.example.org, port is 1234, and the startcode for the regionserver is 1212121212, then the {@link #toString()} would be www.example.org,1234,1212121212.
You can obtain a versioned serialized form of this class by calling {@link #getVersionedBytes()}. To deserialize, call {@link #parseVersionedServerName(byte[])}
