Apache Pinot

Hi Folks, I am experimenting with pinot merge and rollup task
It failed to download the segments from s3.
Couldn't find and config reference for minions similar to server `pinot.server.segment.fetcher.protocols`
Is it possible to use s3 deep store with minions? What is the config for this?

It's on this page, scroll all the way to the bottom <https://docs.pinot.apache.org/basics/data-import/pinot-file-system/amazon-s3|https://docs.pinot.apache.org/basics/data-import/pinot-file-system/amazon-s3>

Thank you! The task was able to download from s3

The merge and rollup worked but got another err
```2022/02/21 16:40:26.018 ERROR [PinotSegmentUploadDownloadRestletResource] [grizzly-http-server-0] Any segments from 'segmentsTo' should not be available in the table at this point```
data returned by brokers is as expected, rows reduced after rollup
but older segments still showed up in ideal state

Tried deleting all segments and re pushing old segments from s3, but deleting all segments didn't cleared the segment lineage
2 of the old segments are effectively hidden from brokers point of view

I'll now try deleting the segment lineage from zk
