Hi @wert_1311    It shows the number of impalad connections are hitting the limit.   You can check on these below points:   1. you can increase the value of "Impala Daemon Max Client Connections" property in the impala configs if really more number of connections are coming. 2. If you think the connections are less but the opened connections are not closing properly and causing the issue you can check the timeouts has been set properly in the Hue safety-valve advance configs.   -idle_session_timeout=3600 -idle_query_timeout=3600      Regards, Chethan YM ...

Hi @yagoaparecidoti ,   I do not think we have such option of blocking but as i know i think you can make it using sentry authorisation. If sentry is enabled in the cluster you should grant only "SELECT" privilege to all the users for all the databases/tables so if the users try any other DDL commands it will throw 'Authorisation exceptions".   Do refer the below documentation: https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/cm_sg_sentry_service.html   If you are using Ranger same can be achieved from ranger also.   Regards, Chethan YM     ...
