------------------------------------
Summary: Hive custom SerDe cannot load DLL added by "ADD FILE"
command
Key: HIVE-6200
URL: https://issues.apache.org/jira/browse/HIVE-6200
Project: Hive
Issue Type: Bug
Reporter: Shuaishuai Nie
Assignee: Shuaishuai Nie
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.
