Hi,
I am facing an issue with one of our Impala Daemon which continuously has error related to “The health test result for IMPALAD_FRONTEND_CONNECTIONS has become bad: There are 0 (Beeswax pool) 123 (Hive Server 2 pool) active client connections, each pool has a configured maximum of 128”
Have checked CM -> Impala -> Charts Library -> check "Active Frontend API connection" this shows too many Hive Server connections
Also checked server's network side and run netstat -an | grep ESTABLISHED | grep 25000 but I see only 2 active connections.
[root@nucleus ~]$ netstat -an | grep ESTABLISHED | grep 25000 tcp 0 0 10.20.20.41:25000 10.20.20.41:49728 ESTABLISHED
tcp 0 0 10.20.20.41:25000 10.20.20.41:49732 ESTABLISHED
Any assistance / guidance in resolving this issue is appericated.
CM / CDH - 6.3.3
Thanks
Wert.

Hi @araujo What are the symptoms of the ticket renewal failure? Are there any error messages anywhere? > We see GSSException on Application logs How did you conclude it's a ticket renewal problem? > We haven’t concluded its a renewal problem however to rule out kerberose issue, we need logs which at the present is not getting written in the location specified in krb5.conf file. Thanks Wert
