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     ...
