Thejas M Nair commented on HIVE-9182:
-------------------------------------
I think the isExtendedAclEnabled check should also be replaced with above
check. That call is checking for dfs.namenode.acls.enabled configuration
parameter which is not applicable to all file systems.
> avoid FileSystem.getAclStatus rpc call for filesystems that don't support acl

> Key: HIVE-9182
> URL: https://issues.apache.org/jira/browse/HIVE-9182
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.14.0
> Reporter: Thejas M Nair
> Assignee: Abdelrahman Shettia
>
> File systems such as s3, wasp (azure) don't implement Hadoop FileSystem acl
> functionality.
> Hadoop23Shims has code that calls getAclStatus on file systems.
> Instead of calling getAclStatus and catching the exception, we can also check
> FsPermission#getAclBit .
> Additionally, instead of catching all exceptions for calls to getAclStatus
> and ignoring them, it is better to just catch UnsupportedOperationException.
