Sergey Shelukhin commented on HIVE-4888:
----------------------------------------

Many of these queries pass for me. It looks like the patch that was tested was the first one
out of the two, which had an issue.
Let me update to trunk and re-submit the patch

> Filter pushdown could be improved. Based on my experiments there's no reasonable way
to do it with DN 2.0, due to DN bug in substring and Collection.get(int) not being implemented.
> With version as low as 2.1 we can use values.get on partition to extract values to compare
to. Type compatibility is an issue, but is easy for strings and integral values.
