Subject [GitHub] orc issue #121: Check the result schema after column selection
Date Tue, 16 May 2017 20:10:02 GMT
Github user omalley commented on the issue:

    https://github.com/apache/orc/pull/121
  
    For external reference, the confusion was that when you use column pruning in ORC, the
resulting schema still has the unselected columns, but they are always null. We should probably
update the documentation to make that clear.
