Russell Melick commented on HIVE-1644:
--------------------------------------
I can send it back out of the index handler, and that seems to function
correctly.
{{{
if (newInputPaths.length() == 0) {
return super.getSplits(job, numSplits);
} else {
FileInputFormat.setInputPaths(job, newInputPaths.toString());
}
}}}
But, this means that we won't use the index to get the splits, so I don't think
our test will work anymore. It will return results from the base table. This
feels like the correct behavior in the long term, even though it breaks the
test.
> use filter pushdown for automatically accessing indexes

> HIVE-1226 provides utilities for analyzing filters which have been pushed
> down to a table scan. The next step is to use these for selecting available
> indexes and generating access plans for those indexes.
