Troubleshooting Orphan Processes after Upgrading OpenSearch Dashboard to 2.7.0

[nik06]

Behavior prior to OSD 2.7.0 :

Launching OSD created a single process that can be easily managed.

Behavior in OSD 2.7.0 :

Launching OSD creates 3 processes :
P1. opensearch-dashboards/bin/opensearch-dashboards
P2. opensearch-dashboards/bin/use_node
P3. opensearch-dashboards/node/bin/node

All these 3 processes get launched with --config flag. Parent process is P1, parent of P2 is P1 and parent of P3 is P2.
Killing P1 doesn't terminate child processes P2 and P3.

Hello @nik06,

Thanks for opening. cc: @AMoo-Miki did this get addressed with:

#3955

If so then a fix is coming for 2.8 but perhaps it's worth a patch release @AMoo-Miki

@nik06 confirmed with @AMoo-Miki this has been addressed in 2.8 (which is currently pending release). Will you be willing to upgrade to 2.8 once it comes out?

Unfortunately, there isn't a 2.7.1 release planned: https://opensearch.org/releases.html.

If you are not able to, please re-open this issue and we can talk about next steps.

Hi @kavilla @AMoo-Miki , thanks for the update. Given that 2.8 release is scheduled for next week, I'll wait for the new version.
