Hitesh Shah commented on TEZ-1529:
----------------------------------

Looks good for the most part. 

Minor comments: 
   - split tests in TestTimelineReaderFactory into 2 functions
   - should tokenDelegationSupported be synchronized from a safety perspective?
   - DEFAULT_SOCKET_TIMEOUT - can this be changed to re-use an existing timeout 
config instead of either using a hardcoded value or introducing a new config. 
   - "    // reads are supported for non-secure cluster from hadoop 2.5 and 
up." - shouldn't this be 2.4? 
   - the file TimelineReaderStrategy is pretty big. Might be good to add a 
summary doc at the very top. 
   - using a version check similar to TestATSHttpClient, can we add some 
version specific tests for 2.4?
