Hi,
I added a new node to my HBase cluster. The PC is the same as the old ones. It 
has 24G memory. When I tried to start regionserver on that node, I got error 
below:

Could not create the Java virtual machine.
Exception in thread "main" java.lang.NoClassDefFoundError: 
Could_not_reserve_enough_space_for_object_heap
Caused by: java.lang.ClassNotFoundException:

Could not find the main class: Could_not_reserve_enough_space_for_object_heap.  
Program will exit.

I tried to decrease the value of HBASE_HEAPSIZE. But it did not help. Does 
anyone can give me some advice?

Thanks
