Github user kkhatua commented on the issue: https://github.com/apache/drill/pull/1203 @arina-ielchiieva You're correct about the inability to shutdown other Drillbits from the WebUI. But, from what @dvjyothsna explained, it seems that this was the result of a technical hurdle with HTTP**S** protocol. My understanding was that issuing shutdown to secure remote nodes won't work because of lack of certificates for those nodes, making it difficult for the remote Drillbit to authenticate the shutdown command. Keeping that in mind, the SHUTDOWN buttons would appear only for unsecured Drillbits, i.e. when Authentication is **_not_** enabled. https://github.com/kkhatua/drill/blob/dd507ea95a7d0ef4904092ef4fc43ee3b44ef058/exec/java-exec/src/main/resources/rest/index.ftl#L100 For setups requiring Authentication, the shutdown button would not appear.
