Thejas M Nair commented on HIVE-6200:
-------------------------------------
As this seems to be required only on windows, how about adding a check if it is
windows before changing the permission ?
> Hive custom SerDe cannot load DLL added by "ADD FILE" command

> When custom SerDe need to load a DLL file added using "ADD FILE" command in
> HIVE, the loading fail with exception like
> "java.lang.UnsatisfiedLinkError:C:\tmp\admin2_6996@headnode0_201401100431_resources\hello.dll:
> Access is denied".
> The reason is when FileSystem creating local copy of the file, the permission
> of local file is set to default as "666". DLL file need "execute" permission
> to be loaded successfully.
> Similar scenario also happens when Hadoop localize files in distributed
> cache. The solution in Hadoop is to add "execute" permission to the file
> after localizationl.
