Owen O'Malley commented on ORC-243:
-----------------------------------
It looks like the only case that isRepeating is set, is when then entire batch
is null. If you look at the DecimalTreeReader.nextBatch it is trying to detect
that case:
{code}
} else if (!result.isRepeating || !result.isNull[0]) {
{code}
Actually, your patch doesn't apply to master. Which branch are you looking at?
> incorrect isRepeating handling in decimal reader
