							 Hi,  On CDP PC > CDW > Virtual Warehouse when I try to login Impala Coordinator Web UI or other UI on that page it does not accept my password, and get error ' Must authenticate with Basic authentication.' I am tried resetting the workload password still it does not allow me to open Impala web ui's. I use the same password to login to Grafana and the password gets accepted.     Appreciate any guidance in resolving this issue.

							 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.
