Bikas Saha commented on TEZ-125:
--------------------------------
We should close this but open a separate jira to enable the AM to get cluster
node/rack info (likely from the TezClient that has access to the YARN protocol
to get this information). This would enable the AM to use the entire cluster
topology knowledge.
> Client should provide rack information in the LocationHint

> Currently, the client only populates host information into the LocationHint,
> and this is converted into rack information by the AM. The client should
> ideally provide all location hint information.
