> Priority: Major

> Noticed by [~huaxiangsun] in his review of HBASE-25055 "Add ReplicationSource
> for meta WALs; add enable/disable w…"
> {quote}bq. Eventually, the meta wal file will be gced and there is no more
> logs in the queue. In that case, the walReader thread will quit. When the
> meta region is moved back, it does not seem that walReader thread will be
> restarted. So it seems that something is broken.
