Based on Impala documentation you need to add that flag, possibly to IMPALA_SERVER_ARGS environment variable on the Impala Daemons.根据Impala 文档，您需要将该标志添加到 Impala 守护进程上的IMPALA_SERVER_ARGS环境变量中。
I'm not sure Cloudera Manager exposes such settings.我不确定 Cloudera Manager 是否公开了此类设置。
Note: Just because you have Cloudera Manager, does not mean you can configure each little detail on the nodes;注意：仅仅因为您有 Cloudera Manager，并不意味着您可以在节点上配置每个小细节； you might need to SSH to individual machines.您可能需要通过 SSH 连接到各个机器。
