chenboat opened a new pull request #5857:
URL: https://github.com/apache/incubator-pinot/pull/5857
## Description
Add an integration test that extends RealtimeClusterIntegrationTest but uses
2 servers and a fake PinotFS as the deep store for segments. This test enables
the peer to peer segment download scheme to test Pinot servers can download
segments from peer servers even the deep store is down. This is done by
controlled injection of failures in the fake PinotFS segment upload api (i.e.,
copyFromLocal) for all segments of even partition number.
Besides standard tests, it also verifies that
(1) All the segments on all servers are in either ONLINE or CONSUMING states
(2) For segments failed during deep store upload, the corresponding segment
download url string is empty in Zk.
