Should I install google map app in each indexer?

[nickcode]

My deployment is:
1 Forwarder + 2 Indexers + 1 Search head.
My data are distributed in 2 indexers, and I only installed Google Map app in the search head.
If I use the Google Map app in the search head to get the geo result, should I install the app in each indexer as well?

Yes. Install it on all search heads and indexers (not forwarders).

The Google Maps app uses a custom command called geoip to lookup the location of each IP address. This custom command isn't sent to the indexers in the knowledge bundle, so you will get errors when you try to search from your search head on the app.

My answer is incorrect...I forgot about the custom command. please see the watsm10's answer...

No, You should not need to install it on an indexer.

When a search head dispatches a search, it sends its knowledge objects to the indexer along with the search request. This includes apps and user objects.
