Subject [jira] [Commented] (HIVE-4888) listPartitionsByFilter doesn't support lt/gt/lte/gte
Date Thu, 26 Sep 2013 23:43:04 GMT


Sergey Shelukhin commented on HIVE-4888:

All these tests have non-int values in int columns. For most of them the problem is solved
by making it JDO-compatible by  doing equal compare as a string, the same way JDO does. For
other one I am looking.

> 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.
