The corresponding code is below and the reason is obvious. Arrays.asList return
a java.util.Arrays$ArrayList but not java.util.ArrayList. Both of them are
inherited from java.util.AbstractList, but the former didn't override the
method add(), so the parent method java.util.AbstractList.add() will be invoked
and the exception threw.
{code}
private void addAuthInfoToConf(Properties authConfig, Configuration conf,
String owner,
String userList) throws IOException {
List<String> users = Arrays.asList(userList.split(","));
users.add(owner);
...
}
{code}
Does anyone occurred on this? I think it's an obvious bug but no one report it,
so please tell me if I misunderstanding it. If it's actually a bug here, then
it can be fixed very easy as below:
{code}
List<String> users = new ArraList<String>(Arrays.asList(userList.split(",")));
{code}
