Amar Kamat commented on HADOOP-3620:
------------------------------------
I think it also makes sense to do the same in the JobTracker. There too the
resolution is async. With HADOOP-3590 getting fixed, the problem is that the
tasks will be scheduled randomly until the node gets resolved. Some of the test
cases assume that the all the TTs are resolved before the job gets submitted
which might not be true always. Thoughts?

> Release 0.18.0 removes the rpc timeout. So the namenode is ok to resolve a
> datanode's network location when the datanode registers. This could remove
> quite a lot of unnecessary code in both datanode and namenode to handle
> asynchronous network location resolution and avoid many potential bugs.
