I made changes due to your suggestions.
Also I deleted spaces in one level directory. Is it better?
`tmp/drill/spill/29014cb9-7eda-f4d1-f216-ce1baf83f58c_majorfragment2_minorfragment0_operator2`
Added set for deleting paths, because
`drill.exec.sort.external.spill.directories` parameter can has several
directories for spooling.
For the case when drillbit process is killed to delete temporary spill
folders I use `fs.deleteOnExit()`.
