Sergey Shelukhin commented on HIVE-17940:
-----------------------------------------

+1... not sure if tests are set up for branch-1 or how stale they are, might be worth it to wait for HiveQA

> When the last row-group in an ORC stripe contains fewer records than specified in {{$\{orc.row.index.stride\}}}, and if a column value is sparse (i.e. mostly nulls), then one sees the following failure when reading the ORC stripe:

> [~sershe] had a fix for this in HIVE-10024, in {{branch-2}}. After running into this in production with {{branch-1}}+, we find that the fix for HIVE-10024 sorts this out in {{branch-1}} as well.
> This is a fairly rare case, but it leads to bad reads on valid ORC files. I will back-port this shortly.
