Subject [jira] [Created] (PHOENIX-2498) Secondary index table is not updated in bulk load

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

             Summary: Secondary index table is not updated in bulk load
                 Key: PHOENIX-2498
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2498
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.5.2
         Environment: CentOs
            Reporter: Afshin Moazami


When using Phoenix map reduce bulk loader to load data from a csv file to a table (myTable)
with a secondary index (myIndex) in schema (mySchema), if I use 

-table mySchema.myTable

data will load only to the myTable, not myIndex.

But, both will be loaded if I use:
-schema mySchema -table myTable

I am not sure if it is a bug or feature, but it is not documented anywhere (or at lease I
couldn't find it)

As a result of the first usage (where index is not loaded), we can have weird scenarios like

select /*+ INDEX(mySchema.myTable myIndex) */* from myTable where myColumn  = 'myValue'

and it returns a row that myColumn is not equal to myValue, because where clause is validated
against the index and the data will be returned from the main table ( I guess)
