Indhumathi27 opened a new pull request, #5953:
URL: https://github.com/apache/hive/pull/5953

   ### What changes were proposed in this pull request?
   Updated the way decimal partition column values are set in vectorized 
execution. It ensures that the full decimal value, including its precision and 
scale, is correctly preserved when loading partition data into the vectorized 
engine.
   
   
   ### Why are the changes needed?
   The previous approach lost decimal precision and scale, causing incorrect 
results for joins and group by operations on partitioned decimal columns when 
vectorization is enabled. The fix ensures correct query results by accurately 
setting the decimal value.
   
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   Testcase added
