             Summary: Add more info to understand the source/scenario of large batch requests exceeding threshold
                 Key: HBASE-18633
                 URL: https://issues.apache.org/jira/browse/HBASE-18633
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.3.1
            Reporter: Vikas Vishwakarma
            Assignee: Vikas Vishwakarma


In our controlled test env, we are seeing frequent Large batch operation detected warnings (as implemented in HBASE-18023). 
We are not running any client with large batch sizes on this test env, but we start seeing these warnings after some runtime. Maybe it is caused due to some error / retry scenario. Could also be related to Phoenix index updates based on surrounding activity in the logs. Need to add more info like table/region name and anything else that will enable debugging the source or the scenario in which these warnings occur.
