veghlaci05 opened a new pull request, #3289:
URL: https://github.com/apache/hive/pull/3289

   
   ### What changes were proposed in this pull request?
   This PR changes the commit time of the Fetch tasks. From now on these tasks 
are committed only upon driver close.
   
   ### Why are the changes needed?
   Fetch tasks were committed inside the 
org.apache.hadoop.hive.ql.Driver#run(java.lang.String) call which was too 
early. The reading can occur only after this point, which can cause issues, if 
the table changes during the read. 
   
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   Manually, and through unit tests
