[GitHub] [incubator-pinot] mcvsubbu opened a new issue #6068: Helix may silently return an empty list if zk connection is lost
mcvsubbu opened a new issue #6068:
URL: https://github.com/apache/incubator-pinot/issues/6068
Helix may return an empty list for instances, or list of children in case where zk connection is lost. This has been worked around by adding a new API in Helix (see https://github.com/apache/helix/pull/160) but the old API was not deprecated in the interface definition.
While we run the periodic broker rebuild task, it is possible to get an empty list of broker instances for a given table, causing us to remove the table from the broker's idealstate , resulting in service disruption.
These have apparently been fixed in Helix 1.0+ but that is a source incompatible change, and we need to do that at some point.
For now, we should at least fix the APIs we know about
