Bernd Mathiske updated MESOS-2057:
----------------------------------
Description:
Add a URI flag to CommandInfo messages that indicates caching. When a URI is
"cached" it is only ever downloaded once for the same user on the same slave as
long as the slave keeps running. This even holds if multiple tasks request the
same URI concurrently. Different URIs from different CommandInfos can be
downloaded concurrently.
No cache eviction, cleanup or failover will be handled for now. Additional
tickets will be filed for these enhancements. (So don't use this feature in
production until the whole epic is complete.)
Depends on MESOS-2056.
