IMPALA-5394: Change ThriftServer() to always use TAcceptQueueServer
- Previously TThreadPoolServer called getTransport() on a client from
the Server thread (the thread that did the accepts).
- TSaslServerTransport->getTransport() called TSaslTransport->open()
- TSaslServerTransport->open() tried to negotiate SASL which calls
read/write
- If read/write blocks indefinitely, the TThreadPoolServer could
not accept connections until tcp_keepalive kicked in.
- Set the underlying TSocket's recvTimeout and sendTimeout before the
TSaslServerTransport->open() and reset them to 0 after open()
completes.
- Added sasl_connect_tcp_timeout_ms flag that defaults to 300000
milliseconds (5 minutes)
- Add the ability for the TAcceptQueueServer to limit the maximum
number of tasks at a time
- Removed the previously unenforced thread limit requests from
StatestoreService, StatestoreSubscriber, CatalogService.
- Changed the remaining Thrift servers to use TAcceptQueueServer.
(hs2/beeswax/network-perf-benchmark)
- The timeout is still needed in TAcceptQueueServer since
SetupConnection follows a similar pattern that TThreadPoolServer
does.
- Removed support for TThreadPool from ThriftServer() since it is
no longer used anywhere. ThriftServer() now always uses
TAcceptQueueServer.
- Deprecated enable_accept_queue_server flag and removed supporting
code.
