Ashutosh Chauhan updated HIVE-6200:
-----------------------------------
Status: Open (was: Patch Available)
Changing of permissions should be moved in downloadResource() method, such that
we change permissions only when files are downloaded. Because, int that case we
are guaranteed to successfully complete chmod operation. Otherwise, we may try
to change permissions of local files (which may not be allowed since we may not
own them).
Also, patch needs a rebase.

> 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.
