"The trigger for this patch is the nodetool remove command, the expected
behaviour is that the error that return from the API would be populate to the
JMX client.
In this first stage the API errors are send as a generic RuntimeException, in a
later phase specific methods would catch this exception and replace it with a
specific one. Note that the thrown exceptions should be one that is known to the client,
or it would fail to handle it and in general should be equivalent to origin.
After this patch a call to the nodetool remove with a bad host name would result in:
./bin/nodetool removenode dcc0477a-b4a7-448a-bc79-27853f61b92d
error: Host ID not found.

java.lang.RuntimeException: Host ID not found.

Urchin JMX Interface
This is the JMX interface for urchin.
Compile
To compile do:
mvn install
Run
The maven will create an uber-jar with all dependency under the target directory. You should run it with the remote jmx enable so the nodetool will be able to connect to it.
java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7199 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -jar target/urchin-mbean-1.0.jar
Setting IP and Port
By default the the JMX would connect to a node on the localhost on port 10000.
The jmx API uses the system properties to set the IP address and Port. To change the ip address use the apiaddress property (e.g. -Dapiaddress=1.1.1.1) To change the port use the apiport (e.g. -Dapiport=10001)
