Ted Yu commented on HBASE-6728: ------------------------------- HBaseServer would continue responding to requests after SizeBasedThrottler.decrease() is called. The following is one example: {code} responseQueue.poll(); responseQueuesSizeThrottler.decrease(call.response.limit()); {code} > [89-fb] prevent OOM possibility due to per connection responseQueue being > unbounded > ----------------------------------------------------------------------------------- > > Key: HBASE-6728 > URL: https://issues.apache.org/jira/browse/HBASE-6728 > Project: HBase > Issue Type: Bug > Reporter: Kannan Muthukkaruppan > Assignee: Michal Gregorczyk > Fix For: 0.94.3, 0.96.0 > > Attachments: 6728.94, 6728-trunk.txt > > > The per connection responseQueue is an unbounded queue. The request handler > threads today try to send the response in line, but if things start to > backup, the response is sent via a per connection responder thread. This > intermediate queue, because it has no bounds, can be another source of OOMs. > [Have not looked at this issue in trunk.
