Gopal V commented on TEZ-3310:
------------------------------
The reason "localhost" is scrubbed is because RM was waiting for "localhost" to
heartbeat to allocate containers.
IIRC, this was because
abfsStore.getAbfsConfiguration().getAzureBlockLocationHost() defaulted to
"localhost".
> Handle splits grouping better when locality information is not available (or
> only when localhost is available)

> Priority: Minor

> This is a follow up JIRA to TEZ-3291. TEZ-3291 tries to handle the case when
> only localhost is specified in the locations. It would be good to improve
> handling of splits grouping when Tez does not have enough information about
> the locality.
