Norbert Luksa updated ORC-600:
------------------------------
Labels: c++ (was: )
> StringDictionaryColumnReader does not update index buffer correctly
> -------------------------------------------------------------------
>
> Key: ORC-600
> URL: https://issues.apache.org/jira/browse/ORC-600
> Project: ORC
> Issue Type: Bug
> Reporter: Norbert Luksa
> Priority: Major
> Labels: c++
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When we are scanning with StringDictionaryColumnReader an encoded batch, ORC
> crashes if we want to read more elements than the current capacity of the
> batch. It can occur eg. with string lists where it's possible that the
> offsets defined in the list overflows in the index buffer of the
> EncodedStringDictionaryBatch.
> To fix we only have to define a resize method for
> EncodedStringDictionaryBatch that also resizes the index buffer.
