Unable to find region using springboot app

whybother — Fri, 16 Sep 2022 13:13:38 GMT

I'm trying to create a simple springboot application that contains hbase-site.xml and various other configuration properties in resources.

App is able to create a connection and during the query phase it seems unable to scan for a valid region that contains the queried table.

We are able to query the table and records using command prompt.

Here's the console log.

Re: Unable to find region using springboot app

The issue was with the app unable to load hbase-site.xml properly. Fixing that resolved the issue.
