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

             Summary: IndexTool should report the number of rows built
                 Key: PHOENIX-5474
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5474
             Project: Phoenix
          Issue Type: Bug
            Reporter: Kadir OZDEMIR
            Assignee: Kadir OZDEMIR
             Fix For: 4.15.0, 5.1.0, 4.14.3


In the old design, the IndexTool MR job mapper first scanned the data table 
rows one by one using a Phoenix client code, then constructed the index rows 
and finally sent these row mutations to region servers to update the rows on 
the index table regions. While doing that, it emitted the counters at the row 
level. In the new design, this entire process is done on the server side 
(within a coprocessor). So, the mapper just issues one RPC call to instruct the 
coprocessor to build the entire table region. Thus, currently it does not 
report the number of rows that have been built, instead it reports the number 
of table regions built.
