Haibo Chen commented on YARN-7933:
----------------------------------

If it's not in our design, I am inclined to remove it at this point in time. 
{quote}Timeline Token verification is at filter layer at the time of http 
connection establishment i.e even before it reaches servlets.
{quote}
Does that mean if two collectors are allocated on the same node, then one AM 
can forge data of another?  This is probably an independent issue that applies 
to the other TimelineCollectorWebservices endpoint,  putEntities(), which we 
can address in another jira.
