---------------------------------
Summary: support more flexible policy for uploading in shared cache
Key: YARN-2781
URL: https://issues.apache.org/jira/browse/YARN-2781
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Sangjin Lee
Today all resources are always uploaded as long as the client wants to upload
it. We may want to implement a feature where the shared cache manager can
instruct the node managers not to upload under some circumstances.
Some examples may be uploading a resource if it is seen more than N number of
times.
This doesn't need to be included in the first version of the shared cache.
