------------------------------
Summary: Some synchronization on ServerManager#onlineServers can
be removed
Key: HBASE-10294
URL: https://issues.apache.org/jira/browse/HBASE-10294
Project: HBase
Issue Type: Task
Reporter: Ted Yu
Priority: Minor
ServerManager#onlineServers is a ConcurrentHashMap
Yet I found that some accesses to it are synchronized and unnecessary.
Here is one example:
{code}
public Map<ServerName, ServerLoad> getOnlineServers() {
// Presumption is that iterating the returned Map is OK.
synchronized (this.onlineServers) {
return Collections.unmodifiableMap(this.onlineServers);
{code}
