@tzulitai ，When I have fixed the problem, I want to write a IT case. But,
in the Yarn IT case:
1、 It uses the yarn mini cluster, which is for testing.I do not know
whether it is using HDFS Delegation token or not.
2、And what's more, the HDFS Delegation Token is used by yarn node manager.
It is difficult to judge whether to have this token or not in yarn client. The
token is set into yarn application context,but the yarn client does not have
API to get yarn application context.
How do you think ? Thanks a lot!
> when deploy flink cluster on the yarn, it is lack of hdfs delegation token.

> 1、I use the flink of version 1.2.0. And I deploy the flink cluster on the
> yarn. The hadoop version is 2.7.2.
> 2、I use flink in security model with the keytab and principal. And the key
> configuration is :security.kerberos.login.keytab: /home/ketab/test.keytab
> 、security.kerberos.login.principal: test.
> 3、The yarn configuration is default and enable the yarn log aggregation
> configuration" yarn.log-aggregation-enable : true";
> 4、 Deploying the flink cluster on the yarn, the yarn Node manager occur the
> following failure when aggregation the log in HDFS. The basic reason is lack
> of HDFS delegation token.

> 5、the hadoop fix the hadoop issue
> 14116(https://issues.apache.org/jira/browse/HADOOP-14116), if there is no
> HDFS delegation token, it will try 20 times after sleeping 1 second. So it
> will cause the flink cluster deploy on yarn is very slowly, it will spent
> about 5 minutes to deploy the cluster with 2 taskmanagers.
