Subject Can I share datas for several map tasks?
Date Tue, 16 Jun 2009 00:11:04 GMT
I want to share some data structures for the map tasks on a same node(not through files),
I mean, if one map task has already initialized some data structures (e.g. an array or a list),
can other map tasks share these memorys and directly access them, for I don't want to reinitialize
these datas and I want to save some memory. Can hadoop help me do this?
