Review comment:
From my read, it seemed like whenever
ServerGauge.LLC_PARTITION_CONSUMING is set to 0 under error conditions (except
for when consumption is complete or we're going from consuming to ONLINE), the
LLRealtimeSegmentDataManager.State is set to ERROR. So it should work for
any such erroneous conditions.
If that's not the case, then we can treat it as part of a bug fix for #6322
In Uber, AFAIK we rely on the ingestion time lag (from Kafka) to determine
problems in ingestions.
