Zhang Dongsheng updated YARN-11231:
-----------------------------------
Component/s: yarn
Description: FSDownload calls createDir in the call method to create the
destinationTmp directory, which is later used as the parent directory to create
the directory dFinal, which is used in doAs to perform operations such as path
creation and path traversal. doAs cannot determine the user's identity, so
there is a problem with setting 755 permissions for destinationTmp here, I
think it should be set to 777 permissions here.
> FSDownload set wrong permission in destinationTmp
