------------------------------------------

             Summary: Upsert Select is returning updated count  is wrong if 
overall count is more than configured batch size
                 Key: PHOENIX-3859
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3859
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.10.0
            Reporter: Maddineni Sukumar
            Assignee: Maddineni Sukumar


If I setup driver with below property 
props.put(QueryServices.MUTATE_BATCH_SIZE_ATTRIB, Integert.toString(50));

And load more than 50 rows, for example 60 rows and then run below upsert 
select query.

int count = conn.createStatement().executeUpdate("Upsert into TableA select * 
from TableA");

Count comes as 120 instead of 60. If I increase batch size to more than 60 and 
try then it gives proper result as 60.
