Hi,I've enabled HA successfully. My directory for the three journal node is not the same accross that 3 journal node.

There are alert of required JournalNode Default Group box. Is it safe to I put anything here? as my journal node location is not the same? It is only for managing that 3 journal node loaction right?

Thanks

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

Thanks @PabitraDas

Alright, done as your suggestion, the cluster is looking good now without the alert

Thanks for the link too.
