[jira] [Created] (HIVE-4189) ORC fails with String column that ends in lots of nulls

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

             Summary: ORC fails with String column that ends in lots of nulls
                 Key: HIVE-4189
                 URL: https://issues.apache.org/jira/browse/HIVE-4189
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
    Affects Versions: 0.11.0
            Reporter: Kevin Wilfong
            Assignee: Kevin Wilfong


When ORC attempts to write out a string column that ends in enough nulls to span an index stride, StringTreeWriter's writeStripe method will get an exception from TreeWriter's writeStripe method

Column has wrong number of index entries found: x expected: y

This is caused by rowIndexValueCount having multiple entries equal to the number of non-null rows in the column, combined with the fact that StringTreeWriter has special logic for constructing its index.
