Jonathan Lawlor commented on HBASE-12266:
-----------------------------------------
Sounds like this issue is related to the heartbeat/keepalive idea in
HBASE-13090.
The idea over there is to track how long a scan has been executing server side
and to return periodic heartbeat/keepalive messages in the event that the scan
is taking a long time. The frequency of these heartbeats messages would be
dependent upon the configured scanner timeout (a more restrictive timeout would
lead to more frequent heartbeat messages). This solution would address the
issue of a slow scan and would also remove the possibility of this dead loop.
Thoughts? Think we could close this one out?
