> 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.
