Jean-Marc Spaggiari commented on HBASE-9806:
--------------------------------------------
They have 16GB by default but I can get 16GB from one and put it on another
one. So. Options are:
1) I can run on a 4 nodes cluster where all nodes will have 16GB
2) I can run on 2 standalone/pseudo-dist servers (1 SSD, 1SATA) with 32GB.
Of course, I also have some nodes where I have only 4GB ;) But I don't think
you are interested but those one ;)
