Jonathan Eagles commented on TEZ-1652:
--------------------------------------

[~pramachandran], this is the first part to getting swimlanes to work with 
10,000 task attempts. First issue is that only 100 entries are returned. Second 
issue is that loading 10,000 tasks is slow.

This patch addresses the first issues. It reads the counters to determine 
number of task attempts to return, defaulting to a very large number is the 
total tasks cant be found. Please review and suggest code improvements. Should 
this logic be moved into the controller as part of a getQueryParams method?

The 2 part of why 10,000 tasks is slow is due to Task attempt serialization as 
part of counter normalization. Do you want to look at improving counter 
normalization speed?

> Issue is that by default, Timeline Server only returns 100 max entity results 
> per query. For query for all task attempts for dag. A limit should be high 
> enough to get all entries and yet provide responsiveness.
