Hi,
Any comments or thoughts on the implications of the newly released feature
from Hadoop 2.3 on the centralized cache? How different it is from RDD?
Many thanks.

We do not currently cache blocks which are under construction, corrupt, or
otherwise incomplete.
Have you tried with a file with more than 1 block?
And
I tried centralized cache step by step following the apache hadoop oficial
website, but it seems centralized cache doesn't work.
see :

.
Can anyone succeed?
