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

             Summary: Data type promotion does not work w/ partition stats index
                 Key: HUDI-8587
                 URL: https://issues.apache.org/jira/browse/HUDI-8587
             Project: Apache Hudi
          Issue Type: Improvement
          Components: metadata
            Reporter: sivabalan narayanan


When a INTEGER column is evolved to LONG, sometimes we have to merge stats from 
different files together and parittion stats breaks w/ class cast exception 
under such circumstances. 

 

if possible, we should detect and throw user readable errors instead of 
throwing random errors.
