Zhihong Yu commented on HBASE-3850: ----------------------------------- Should we add tablename to the log as well ? I found only one implementation for RegionScanner: {code} class RegionScannerImpl implements RegionScanner { src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java {code} I didn't find much more information in RegionScannerImpl that would help us debug. > Log more details when a scanner lease expires > --------------------------------------------- > > Key: HBASE-3850 > URL: https://issues.apache.org/jira/browse/HBASE-3850 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Benoit Sigoure > Priority: Critical > Attachments: HBASE-3850.trunk.v1.patch > > > The message logged by the RegionServer when a Scanner lease expires isn't as > useful as it could be. {{Scanner 4765412385779771089 lease expired}} - most > clients don't log their scanner ID, so it's really hard to figure out what > was going on. I think it would be useful to at least log the name of the > region on which the Scanner was open, and it would be great to have the > ip:port of the client that had that lease too. -- This message is automatically generated by JIRA.
