ThriftServer".
INLINE COMMENTS
src/main/java/org/apache/hadoop/hbase/thrift/CallQueue.java:131 I searched
HBase code base and didn't find any call to drainTo().
For simplicity and correctness, I think patch v8 looks better.
If drainTo() becomes performance bottleneck, we can come back optimizing it.

> It will be useful to have some metrics (queue length, waiting time,
> processing time ...) similar to Hadoop RPC server. This allows us to monitor
> system health also provide a tool to diagnose the problem where thrift calls
> are slow.
