Nick Dimiduk updated HBASE-13996: --------------------------------- Fix Version/s: (was: 1.1.2) This looks like a feature enhancement, not a bug fix. Hence dropping from 1.1.x line. > Add write sniffing in canary > ---------------------------- > > Key: HBASE-13996 > URL: https://issues.apache.org/jira/browse/HBASE-13996 > Project: HBase > Issue Type: New Feature > Components: canary > Affects Versions: 0.98.13, 1.1.0.1 > Reporter: Liu Shaohui > Assignee: Liu Shaohui > Fix For: 2.0.0, 0.98.14 > > Attachments: HBASE-13996-v001.diff > > > Currently the canary tool only sniff the read operations, it's hard to > finding the problem in write path. > To support the write sniffing, we create a system table named '_canary_' in > the canary tool. And the tool will make sure that the region number is large > than the number of the regionserver and the regions will be distributed onto > all regionservers. > Periodically, the tool will put data to these regions to calculate the write > availability of HBase and send alerts if needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
