Subject How Can I close dead session in Impala 2.3.0
Date Wed, 29 Nov 2017 09:08:40 GMT
Hi guys,

         Due to some reason , some session on impala hangs but not closed , service_thread
is full and no more new session can be setup , but the client of dead session is no longer
exist, just Increase service_thread is not a solution cause it just extends a little bit the
service time .
         Is there any variable or solution can be set to manage this kind of dead sessions
?
         Tried option Cidle_session_timeout , but this option only set the session expire
to TRUE but cant close it .

         Impala Version : 2.3.0

Thanks
Carl
