Ankit Singhal commented on PHOENIX-4458:
----------------------------------------

[~asko], As per your jstack, index writers are also using the same pool(default) of handlers which is used for the scan. 
So, until you upgrade to 4.12 (which has PHOENIX-3994 to automatically configures the RPC controller factory for indexer), you need to manually set the below configuration in hbase-site.xml of the server (ensure that these configuration doesn't exist in hbase-site.xml of the client).

{code}
<property>
  <name>hbase.region.server.rpc.scheduler.factory.class</name>
  <value>org.apache.hadoop.hbase.ipc.PhoenixRpcSchedulerFactory</value>
  <description>Factory to create the Phoenix RPC Scheduler that uses separate queues for index and metadata updates</description>
