------------------------------------

             Summary: Exception in thread "Container Allocator Thread" java.lang.ClassCastException: org.apache.hadoop.security.token.Token cannot be cast to org.apache.hadoop.security.token.TokenIdentifier
                 Key: SAMZA-780
                 URL: https://issues.apache.org/jira/browse/SAMZA-780
             Project: Samza
          Issue Type: Bug
          Components: yarn
    Affects Versions: 0.10.0
            Reporter: Michael Martin
            Priority: Blocker


When running a Samza job in Hadoop 2.6.0 against the latest source code I get the following error:

{code}
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
Exception in thread "Container Allocator Thread" java.lang.ClassCastException: org.apache.hadoop.security.token.Token cannot be cast to org.apache.hadoop.security.token.TokenIdentifier
	at org.apache.samza.job.yarn.ContainerUtil.startContainer(ContainerUtil.java:174)
	at org.apache.samza.job.yarn.ContainerUtil.runContainer(ContainerUtil.java:109)
	at org.apache.samza.job.yarn.ContainerAllocator.run(ContainerAllocator.java:66)
	at java.lang.Thread.run(Thread.java:745)
{code}

The offending line of code is attempting an invalid cast, and instead should be doing something like:
{code}
TokenIdentifier token = ((Token) iter.next()).decodeIdentifier();
{code}

See https://github.com/apache/hadoop/blob/release-2.6.0/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/token/Token.java for reference
