jadami10 opened a new issue, #9645:
URL: https://github.com/apache/pinot/issues/9645
In trying to use the new `/tables/{tableName}/timeBoundary` API, we saw a
lot of errors with `Could not validate table segment status`. We traced this to
`UnknownHostException` due to the fact that we replace hosts throughout the
day, and the controller caches the admin endpoint for servers. #4678 added a
cache for the admin endpoint, but at 6 hours long, this means the controller
can take quite a while to update. Many of our tables are refreshed hourly, so
this leads to many failures.
The proposal here would be to either:
- lower the cache interval to ~1 minute which is a reasonable retry window
- listen to ZK config changes and update the cache
