Siddharth Seth commented on TEZ-624:
------------------------------------
bq. getTaskIndex()
I meant vertexIndex - that'll hopefully be the same for all tasks belonging to
the same vertex.
UniqueIdentifier is convenient - but once all of these are exposed, that can be
constructed - since these are the primitives used to construct it.
Do you mind adding an InputIdx as well - just to stay consistent across the
three context objects - even though it's not used at the moment.
Avoiding new JobConf(conf) in YARNRunner is a nice to have change (can be
short-circuited to just run the code which is run inside of the method call to
figure out new / old API - a helper may already exist for this in MRHelpers) -
shouldn't be invoked too many times when running an MR job.
Otherwise looks good.
