> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Tanuj Khurana
> Assignee: Tanuj Khurana
> Priority: Major
>
> An idle RegionServer can stay stuck in STORE_AND_FORWARD mode indefinitely,
> wedging the whole replication group at ACTIVE_NOT_IN_SYNC, because its
> promotion guard scans a shared directory instead of a per-RS signal. A RS in
> STORE_AND_FORWARD promotes back to SYNC_AND_FORWARD via
> processNoMoreRoundsLeft only when the caught-up guard passes. That guard
> scanned the next round's shard — a shared directory holding
> every active RS's live OPENFORWRITE rotation writer. Because that shard is
> essentially never empty while any peer is writing, an idle RS which never
> processes any file in the OUT directory can remain pinned in
> STORE_AND_FORWARD, wedging the group at ACTIVE_NOT_IN_SYNC indefinitely.
