Samarth Jain commented on PHOENIX-3974:
---------------------------------------
With 0.98 we noticed that we had to set both the RPCControllerFactory as well
as the RPCSchedulerFactory configs. See this:
https://issues.apache.org/jira/browse/PHOENIX-3360?focusedCommentId=15968697&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15968697
And +1 to what [~lhofhansl] suggested. Maybe the change should be here?
{code}
if (upsertSelectTable != null) {
isUpsert = true;
projectedTable = deserializeTable(upsertSelectTable);
+
env.getConfiguration().setClass(RpcControllerFactory.CUSTOM_CONTROLLER_CONF_KEY,
ServerRpcControllerFactory.class,
+ RpcControllerFactory.class);
targetHTable = new HTable(env.getConfiguration(),
projectedTable.getPhysicalName().getBytes());
selectExpressions =
deserializeExpressions(scan.getAttribute(BaseScannerRegionObserver.UPSERT_SELECT_EXPRS));
values = new byte[projectedTable.getPKColumns().size()][];
{code}

> In PHOENIX-3360 we were trying to avoid using index rpc on client side,
> setting controller manually in Indexer. But after we moved index creating to
> server side there is another set of RS-RS communication that comes from
> UngroupedAggregateRegionObserver with regular priority. That may cause
> distributed dead lock when all handlers are occupied by index create scanners
> for user table and inside they are trying to send index updates. To prevent
> it we need to set controller in UngroupedAggregateRegionObserver in the
> similar way like we did in Indexer.
