[SPARK-8005][SQL] Input file name
Users can now get the file name of the partition being read in. A thread
local variable is in `SQLNewHadoopRDD` and is set when the partition is
computed. `SQLNewHadoopRDD` is moved to core so that the catalyst package can
reach it.
This supports:
`df.select(inputFileName())`
and
`sqlContext.sql("select input_file_name from table")`
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/JDrit/spark input_file_name
