Comment:
nodetool streams is replaced by nodetool netstats

  
  Monitoring the status of streaming on both Source and Destination nodes can 
be found under the `org.apache.cassandra.streaming.StreamingService` MBean.  
The `Status` attribute gives an easy indication of what a node is doing with 
respect to streaming. The operations `getOutgoingFiles(host)` and 
`getIncomingFiles(host)` each return a list of strings describing the status of 
individual files being streamed to and from a given host. Each string follows 
this format:  `[path to file] [bytes sent/received]/[file size]` If you think 
that streaming is taking too long on your cluster, the first thing you should 
do is check `StreamSources` or `StreamDestinations` to figure out which hosts 
are streaming files.  Use those hosts as inputs to `getOutgoingFiles()` or 
`getIncomingFiles()` to check on the status of individual files from the 
problematic source and destination nodes.  Streaming is conducted in 32MB 
chunks, so you should refresh the file status after a few seconds to see if the 
sent/received values change.  If they do not change, or change more slowly than 
you'd like, something is wrong.
  
- The streaming status can also be monitored using {{{nodetool -h <hostname/IP> 
streams}}}
+ The streaming status can also be monitored using {{{nodetool -h <hostname/IP> 
-p <jmxport> netstats}}}
