Hello,

Recently, I started noticing an interesting pattern. When I execute 
"removenode", a subset of the nodes that now own the tokens result it in a CPU 
spike / disk activity, and sometimes SSTables on those nodes shoot up.

After looking through the code, it appears to me that below function forces 
data to be streamed from some of the new nodes to the node from where 
"removenode" is kicked in. Is my understanding correct ?

https://github.com/apache/cassandra/blob/d384e781d6f7c028dbe88cfe9dd3e966e72cd046/src/java/org/apache/cassandra/service/StorageService.java#L2548

Our nodes don't run very hot, but it appears this streaming causes them to have 
issues. Have other people seen this ?

Thanks !
