> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers

> 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.
