Hi,I'm a student in Tsinghua university, i'm trying to deploy Crail, but i ran 
into some issues, could you please help me?

it seems that the storage limit is set to 1GB, and i can't find the right way 
to configure it, my crail-site.conf is like this:

//////////////////////////////////////////////////////////////////////////////////////////////////////////////

crail.namenode.address            crail://aep4-ib0:9060
