>             Project: Hadoop YARN
>          Issue Type: Sub-task
>    Affects Versions: 2.4.0
>            Reporter: Mohammad Kamrul Islam
>            Assignee: Mohammad Kamrul Islam
>             Fix For: 2.4.1

>         Attachments: YARN-1962.1.patch, YARN-1962.2.patch

>
> Since Timeline server is not matured and secured yet, enabling  it by default 
> might create some confusion.
> We were playing with 2.4.0 and found a lot of exceptions for distributed 
> shell example related to connection refused error. Btw, we didn't run TS 
> because it is not secured yet.
> Although it is possible to explicitly turn it off through yarn-site config. 
> In my opinion,  this extra change for this new service is not worthy at this 
> point,.  
> This JIRA is to turn it off by default.
> If there is an agreement, i can put a simple patch about this.
