Subject [jira] [Created] (HBASE-13996) Add write sniffing in canary
Date Tue, 30 Jun 2015 07:28:06 GMT
Liu Shaohui created HBASE-13996:

             Summary: 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
            Reporter: Liu Shaohui
            Assignee: Liu Shaohui

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.
