> URL: https://issues.apache.org/jira/browse/HBASE-13873
> Project: HBase
> Issue Type: Bug
> Components: integration tests
> Affects Versions: 0.98.13
> Reporter: sunyerui
> Fix For: 0.98.14

>
> When run IntegrationTestIngestWithACL on distributed clusters with kerberos
> security enabled, the method addAuthInfoToConf() in LoadTestTool will be
> invoked and throws UnsupportedOperationException, stack as follows:

> 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
> ArrayList<String>(Arrays.asList(userList.split(",")));
> {code}
