Steve Loughran commented on HADOOP-5731:
----------------------------------------
Incidentally, before anyone says "add that permission", this is the permissions
file that I believe I'm using
{code}
grant {
permission java.security.AllPermission;
};
// Standard extensions get all permissions by default
grant codeBase "file:${java.home}/lib/ext/*" {
permission java.security.AllPermission;
};
{code}
That is: all rights should have been granted.
People who aren't running hadoop services under a security manager won't
encounter this problem, so I'm marking it as minor.
