James Taylor commented on PHOENIX-3994:
---------------------------------------

One other question: shouldn't we be using the coprocessor based HTable factory 
to get this HTable. Getting an HTable in this way I don't think is recommended:
{code}
     private void commitBatch(Region region, List<Mutation> mutations, byte[] 
indexUUID, long blockingMemstoreSize,
@@ -392,7 +409,7 @@ public class UngroupedAggregateRegionObserver extends 
BaseScannerRegionObserver
         if (upsertSelectTable != null) {
             isUpsert = true;
             projectedTable = deserializeTable(upsertSelectTable);
-            targetHTable = new HTable(env.getConfiguration(), 
projectedTable.getPhysicalName().getBytes());
+            targetHTable = new HTable(upsertSelectConfig, 
projectedTable.getPhysicalName().getBytes());
{code}

> During PHOENIX-3360 we tried to remove dependency on 
> hbase.rpc.controllerfactory.class property in hbase-site.xml since it cause 
> problems on the client side (if client is using server side configuration, 
> all client request may go using index priority). Committed solution is using 
> setting the controller factory programmatically for coprocessor environment 
> in Indexer class, but it comes that this solution doesn't work because the 
> environment configuration is not used for the coprocessor connection 
> creation. We need to provide a better solution since this issue may cause 
> accidental locks and failures that hard to identify and avoid.
