Michael Stack created HBASE-25145:
-------------------------------------

             Summary: WALReader quits if nothing to replicate (and won't restart)
                 Key: HBASE-25145
                 URL: https://issues.apache.org/jira/browse/HBASE-25145
             Project: HBase
          Issue Type: Sub-task
            Reporter: Michael Stack


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.

This issue is about writing a test to run the above scenario and fix any probs. found.
