Hi all,

I want make sure that yarn shared cache and distributed cache whether used
memory or not.

I didn't find the implementation that store data in memory, and it just
store data in hdfs(disk)

If it didn't use memory, dose it have any chance to change Yarn shared
cache, so it can store specific data in memory, maybe it could let
Mapreduce much faster.

Thanks in advanced

BR,
Kevin Su
