Our previous change is blocking outDir to be . during CAS download. Also there is a bug that getAbsPath() will not really return a abs path if base is relative path, like foo/bar (it will return a relative path based on foo/bar instead)
It is not necessary for blocking outDir to be ., we should allow download to happen as long as the output files are not escaping from outDir. This CL reslove the base (outDir) to an absolute path then generate the full path for output files.
