>          Components: timelineserver
>    Affects Versions: YARN-2928
>            Reporter: Joep Rottinghuis

> Currently we ignore (swallow) exception from the HBase side in many cases 
> (reads and writes).
> Also, on the client side, neither TimelineClient#putEntities (the v2 flavor) 
> nor the #putEntitiesAsync method return any value.
> For the second drop we may want to consider how we properly bubble up 
> exceptions throughout the write and reader call paths and if we want to 
> return a response in putEntities and some future kind of result for 
> putEntitiesAsync.
