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? > Slow Scan can cause dead loop in ClientScanner > ----------------------------------------------- > > Key: HBASE-12266 > URL: https://issues.apache.org/jira/browse/HBASE-12266 > Project: HBase > Issue Type: Bug > Components: Scanners > Affects Versions: 0.96.0 > Reporter: Qiang Tian > Priority: Minor > Attachments: 12266-v2.txt, HBASE-12266-master.patch > > > see http://search-hadoop.com/m/DHED45SVsC1. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
