Subject RE: Region servers down...

My cluster is in this way.  
Hadoop & HBase are deployed on different machine. 
HBase use the hdfs of Hadoop.  


4 CPU & 6 G RAM


HBase  HMaster & RS  RS  RS

At first,we deployed all machine Hadoop & HBase & Mapreduce, we found it was easy
to make RS down because of memory problem.  
Task of Map/Reduce will eat too much memeory. And Hbase need to use swap. So we divided them.

Is this the reason? Or memory is tow small?
