Karam Singh commented on YARN-2449:
-----------------------------------

Similarly If you run hadoop applications e.g. without settings 
hadoop.http.filter.initializers with timelineserver enabled
e.g :
{code}
hadoop jar 
/usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples-2.5.0.2.2.0.0-532.jar pi 10 
10
{code}

Application submission fails with following type of excpetion:
{code}
org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field 
"About" (Class 
org.apache.hadoop.yarn.api.records.timeline.TimelineDelegationTokenResponse), 
not marked as ignorable
 at [Source: N/A; line: -1, column: -1] (through reference chain: 
org.apache.hadoop.yarn.api.records.timeline.TimelineDelegationTokenResponse["About"])
{code}

> Timelineserver returns invalid Delegation token in secure kerberos enabled 
> cluster when hadoop.http.filter.initializers are not set

>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: timelineserver
>    Affects Versions: 2.6.0
>         Environment: Deploy security enabled cluster is ATS also enabled and 
> running, but no hadoop.http.filter.initializers set in core-site.xml
>            Reporter: Karam Singh
>            Priority: Critical
>
> Timelineserver returns invalid Delegation token in secure kerberos enabled 
> cluster when hadoop.http.filter.initializers are not set
> Looks in it is regression from YARN-2397
> After YARN-2397. when no hadoop.http.filter.initializers is set
> Now when try fetch DELEGATION token from ATS, it returns invalid token
> Tried to fetch timeline delegation by using curl commands :
> {code}
> 1. curl -i -k -s -b 
> '/grid/0/hadoopqe/y6/YarnWSAPISubmitAppKillApp/timeline-cookie.txt' 
> 'http://atshost:8188/ws/v1/timeline?op=GETDELEGATIONTOKEN&renewer=hrt_qa'
> Or
> 2. curl -i -k -s --negotiate -u : 
> 'http://atshost:8188/ws/v1/timeline?op=GETDELEGATIONTOKEN&renewer=test_user'
> {code}
> Return response is for both queries: 
> {code}
> {"About":"Timeline API"}
> {code}
> Whereas before YARN-2397 or if you set hadoop.http.filter.initializers = 
> TimelineAuthenticationFilterInitializer or AuthenticationFilterInitializer
> First query returns DT and Second used to fail
