但当我执行脚本时,我收到以下错误:
fatal: [52.69.71.248]: FAILED! => {"failed": true, "msg": "The conditional check '(inventory_hostname in groups['slaves']) and ( spark-slave.stat.exists == False )' failed. The error was: error while evaluating conditional ((inventory_hostname in groups['slaves']) and ( spark-slave.stat.exists == False )): 'slave' is undefined\n\nThe error appears to have been in '/opt/ansible-role-spark/tasks/download.yaml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: Download Spark\n ^ here\n"}
谁能帮我找出我犯的错误吗。
