Zhiyuan Yang commented on TEZ-3856:
-----------------------------------
The logic looks correct, but this api doesn't seem to fit in Vertex interface.
{code}
TezCounters getInputCounters();
{code}
>From interface perspective, Vertex shouldn't be aware of input counters, not
>to mention some vertices doesn't even have input counter.
I see you want to extract specific counters instead of full counters. There is
concept of counter group in original counter framework. In your case a more
generic API getCounter(groupName) is better. You can group input counters and
get them by group. This is also useful later when you want to extract other
specific counters.

> Hive would like to publish some counters related to input splits during split
> generation. Tez doesn't expose TezCounters via InputIntializerContext. This
> ticket is to expose TezCounters via InputInitializerContext so that counters
> can be accessed during split generation.
