回复: How Can I close dead session in Impala 2.3.0

[445484...@qq.com]

Hi 董博:
        you can configure the TCP Keepalive parameters for Linux.
        Example:
            net.ipv4.tcp_keepalive_time = 1200
            net.ipv4.tcp_keepalive_intvl = 30
            net.ipv4.tcp_keepalive_probes = 3
        I hope the suggestion helpful.

主题： How Can I close dead session in Impala 2.3.0
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 can’t close it .
         
         Impala Version : 2.3.0
 
Thanks 
Carl
