Russell Melick updated HIVE-1644:
---------------------------------
Attachment: HIVE-1644.18.patch
patch 18
I moved that logic into a helper method, but I'm not seeing the settings being
changed in build/ql/tmp/hive.log
When I have the unit test use a predicate like key=86 instead of key > 45 AND
key < 55, I see the following error
{{{
java.lang.IllegalArgumentException: Can not create a Path from an empty string
at org.apache.hadoop.fs.Path.checkPathArg(Path.java:82)
at org.apache.hadoop.fs.Path.<init>(Path.java:90)

}}}
It seems like this is causing a problem when there are no blocks to return.

> down to a table scan. The next step is to use these for selecting available
> indexes and generating access plans for those indexes.
