Russell Melick commented on HIVE-1644:
--------------------------------------
Unfortunately, having an empty array gives out of bounds exceptions.
{{
java.lang.ArrayIndexOutOfBoundsException: 0
[junit] at
org.apache.hadoop.mapred.FileInputFormat.setInputPaths(FileInputFormat.java:309)
}}
I tried looking through the code at other places we call setInputPaths. In a
few places, we create a directory by calling
{{
Path dir = new Path(System.getProperty("test.data.dir", "."));
FileInputFormat.setInputPaths(job, dir);
}}
I tried using this, but unfortunately, this also gives an exception.
{{
java.io.IOException: cannot find dir = file:/Users/rmelick/hive/ql/mapred in
pathToPartitionInfo:
[pfile:/Users/rmelick/hive/build/ql/test/data/warehouse/temp]
}}
The ql/mapred directory does not exist on my computer, but I also tried
changing it to just hive/ql, and it also failed with the same exception. I'm
not sure if TestFlatFileInputFormat:146 is creating the temp file like you were
thinking. I haven't tried doing it like that.

> 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.
