> Improve RSGroupInfoManagerImpl#getDefaultServers()
> --------------------------------------------------
>
> Key: HBASE-22009
> URL: https://issues.apache.org/jira/browse/HBASE-22009
> Project: HBase
> Issue Type: Improvement
> Components: rsgroup
> Reporter: Xiang Li
> Assignee: Xiang Li
> Priority: Minor
> Fix For: 3.0.0, 2.2.0, 1.5.1, 2.2.1
>
> Attachments: HBASE-22009.branch-1.000.patch,
> HBASE-22009.master.000.addendum.patch, HBASE-22009.master.000.patch,

> {code:title=RSGroupInfoManagerImpl.java|borderStyle=solid}
> private SortedSet<Address> getDefaultServers() throws IOException {
> SortedSet<Address> defaultServers = Sets.newTreeSet();
> for (ServerName serverName : getOnlineRS()) {
> Address server = Address.fromParts(serverName.getHostname(),
> serverName.getPort());
> boolean found = false;
> for (RSGroupInfo rsgi : listRSGroups()) {
> if (!RSGroupInfo.DEFAULT_GROUP.equals(rsgi.getName()) &&
> rsgi.containsServer(server)) {
> found = true;
> break;
> }
> }
> if (!found) {
> defaultServers.add(server);
> }
> }
> return defaultServers;
> }
> {code}
> That is a logic of 2 nest loops. And for each server, listRSGroups()
> allocates a new LinkedList and calls Map#values(), both of which are very
> heavy operations.
> Maybe the inner loop could be moved out, that is
> # Build a list of servers of other groups than default group
> # Iterate each online servers and check if it is in the list above. If it is
> not, then it belongs to default group.
