Hello @muslihuddin , Please note, while enabling HA, CM puts all 3 Journal Nodes into a single group call "Default Group" by default assuming you are going to use the same config value for the 3 JN directories. Since you are using /app/jn for one node and /data/jn for the other 2 JN nodes, it created two separate JN config groups. However, to prevent the CM alert, you can mention /data/jn in the JN default group config so that 2 JNs will be part of the Default config group rather than a separate one, and the 3rd JN will continue to operate in a separate config group till you use /data/jn directory as its edits directory.
Just in case you need to change the JN directory on any JN refer teh steps here - https://docs.cloudera.com/documentation/enterprise/latest/topics/cm_mc_jn.html
