> Empty query results when using results cache and query temp dir, results

> If the scratchdir for temporary query results and the results cache dir are
> in different filesystems, moving the query from the temp directory to results
> cache will fail.
> Looking at the moveResultsToCacheDirectory() logic in QueryResultsCache.java,
> I see the following issues:
> - FileSystem.rename() is used, which only works if the files are on the same
> filesystem. Need to use something like Hive.mvFile or something similar which
> can work between different filesystems.
> - The return code from rename() was not checked which might possibly have
> caught the error here. This may not be applicable if a different method from
> FS.rename() is used in the proper fix.
> With some filesystems (noticed this with WASB), if FileSystem.rename()
> returns false on failure rather than throwing an exception, then this results
> in empty results showing up for the query because the return code was not
> checked properly.
